    Prof. Rennan Barkana

    Professor Rennan Barkana studies the formation and evolution of the first stars. He constructs models in order to predict the properties of the galaxies in which the first stars formed, and studies ways to study these early galaxies, especially via radio-wave radiation from hydrogen atoms at a wavelength of 21 cm.

    He led a study published in 2012 that proposed a new method for detecting the first stars from the early era when the age of the Universe was only one percent of its current age. Another ground-breaking study (end of 2013) predicted for the first time the observational signatures of black holes in the early galaxies resulting from the heating of the cosmic gas when the Universe was half a billion years old.

    Dr. Omer Bromberg

    My main field of interest is relativistic astrophysics. Currently I’m studying relativistic jets that are ejected from the supermassive black-holes at the cores of active galaxies (AGNs), and from stellar mass black-holes or neutron stars that have just been formed.  These jets are responsible to some of the most luminous and energetic phenomena we know like: gamma-ray bursts (GRBs), blazars, microquasars and possibly some type of highly energetic supernovae. They pass tremendous amount of energy to the galactic and to the inter galactic medium, and affect the growth rate of galaxies and the star formation rate in them. However despite almost 4 decades of research, we still don’t know much about the physical processes that makes them work, and they way they interact with their surroundings.


    My study involves building analytical models of the jets and running state of the art simulations of hydrodynamic and magnetic jets. For the simulations I am using a local cluster of 1500 cores that is dedicated for my group and supercomputers in universities abroad.   


    Prof. Amir Levinson

    Prof. Ehud Nakar

    Main field of interest is high-energy astrophysics and in particular the physical processes that are active in sources of high energy radiation, cosmic-rays, neutrinos and gravitational waves.

    Among the astrophysical phenomena that are being explored are gamma-ray bursts, supernovae and soft gamma-repeaters. Physical processes that are studied include colissionless and radiation mediated shocks, shock breakouts, particle acceleration, relativistic hydrodynamics and radiative transfer. In the past he also studied topics in complex systems and nonlinear dynamics.

    Prof. Tsevi Mazeh

    Tsevi Mazeh is Professor of Physics & Astronomy at Tel Aviv University, where he has served as researcher and lecturer since 1979. 
    Throughout his career Prof. Tsevi Mazeh has functioned as both theorist and observer. Early on, as far back as his graduate student days at the Hebrew University of Jerusalem, Mazeh became interested in the dynamics of interacting multi-body stellar systems. His PhD dissertation was a theoretical study of the ``induced eccentricity" of an inner stellar binary-pair by a distant bound perturber star. This effect has been observed not only in binary stars, but also in the evolutionary dynamics of the recently discovered planetary systems. Mazeh's early interest and expertise in stellar dynamics played a crucial role in the discovery of extra-solar planets.
    In 1984 Mazeh initiated the first ever "radial-velocity" search for extra-solar planets in pursuit of his paradigm-shaking hypothesis that massive planets could exist close to their parent stars, at that time widely believed to be impossible. Mazeh's observations, carried out with Dave Latham (Harvard) and in cooperation with Michel Mayor (Geneva) provided the breakthrough discovery in 1989 of the first known massive candidate for extra-solar planet HD114762b. In 2000, Mazeh led the research and discovery of the planet around the star HD209458, enabling its subsequent detection as the first known transiting (eclipsing) planet.

    Mazeh is leading an international effort to detect planets and brown-dwarfs by novel relativistic effects. This research is supported by a highly prestigious 2M euro Advanced Grant awarded to Prof. Mazeh by the European Research Council (ERC) in 2010. Mazeh's team has already detected the first known relativistic beaming planet – Kepler 76.

    Prof. Mazeh is a popular writer and public speaker on Astronomy, History of Science, and Science and Religion. He published a book "Introduction to Special Relativity" (2005); Edited, together with Pinchas Leizer, Drishat Shalom - Reading Peace and Justice in the Torah (2010). Hr chaired the left-wing political movement "Netivot Shalom" for five years.

    • In another line of research, we investigate ionic and polyelectrolyte solutions, their interactions with charge interfaces and bio-membranes, and their response to external electric fields.


    Prof. Shimshon Bar-Ad

    The group of Prof. Shimshon Barad is conducting experimental research in several sub-fields of modern optics, including nonlinear optics, quantum optics, ultrafast optical spectroscopy, and optical characterization of magnetic systems. At present the research in nonlinear optics focuses on the fluid-like propagation of light in self-defocusing nonlinear media, and the possibility of using this analogy to hydrodynamics to construct an all-optical analog event horizon and demonstrate analogs of Hawking radiation. This research is carried out in collaboration with the theory group of Prof. Victor Fleurov. The research in quantum optics, carried out in collaboration with the theory group of Prof. Lev Vaidman, involves weak measurements that demonstrate "which path" paradoxes in nested interferometers. The optically-induced insulator-metal phase transition in vanadium oxide is studied in collaboration with the group of Dr. Alon Bahabad at the School of Electrical Engineering at Tel Aviv University, and the group of Prof. Ivan K. Schuller at the Department of Physics at the University of California, San Diego. The studies of magnetic systems are also carried out in collaboration with Prof. Schuller’s group, and focus on dense arrays of interacting magnetic nano-dots.

    Dr. Moshe Ben Shalom

    Interest is focused on probing fundamental physics in layered two-dimensional (2D) hetrostructure and realizing new concepts in solid-state devices towards future technologies.  Layered structures are assembled by extracting various one-atom-thick crystals, and then placing them one on top of the other as desired (like LEGO blocks). The intrinsic 2D nature of these materials comes from the strong covalent bonds in the plane versus the weak Van der Waals interactions between the layers. It supports ultimately thin crystals with superb structural, mechanical, electronic, phononic and optical properties as well as extreme flexibility and control over these properties in comparison to traditional 2D systems. Graphene, for example, is the strongest, most stiff and yet the most flexible, thinnest and yet impermeable to other atoms, as well as the best charge and heat conducting material. Hexagonal boron nitride (hBN), another layered materials, is an excellent dielectric (insulator), very strong, chemically inert, and provides an outstanding match to graphene. Among other layered materials one can also find single atom thick superconductors, direct and in-direct semiconductors, and even ferromagnetic crystals. The ability to stack these materials together on the atomic scale and to form nearly perfect interfaces brings up many opportunities and ideas for novel electronic phenomena in innovative device architectures.


    The assembly and surface characterization of the structures is done in a dedicated laboratory clean room. Design and fabrication of the studied devices is done by advances electron and ion beam lithography in the TAU nano-centre. Measurements of charge transport, heat transport and magnetometery are performed in a temperature range of 400-0.01 K and under magnetic fields up to 14 Tesla.

    Prof. Yoram Dagan

    Materials in which electrons are strongly interacting with each other exhibit variety of exotic properties such as: high temperature superconductivity, colossal magnetoresistance, ferroelectricity, magneto-electric effects in multiferroic materials. Examples for such materials are: cuprates, manganites, nickelates, organic superconductors, dilute magnetic semiconductors, ferroelectrics, oxide interfaces and many more. Generally speaking, small stimulus results in a large change in one or more physical property.

    In our laboratory we study the electronic structure and the nature of the phase transitions of such materials by tuning control parameters such as chemical doping, epitaxial strain, external electric or magnetic fields etc.

    One of the advantages of our group is the ability to make materials and study their physical properties in one place. Our laboratory is equipped with a pulsed laser deposition facility controlled by a high pressure RHEED (reflection high energy electron diffraction), advanced and automated low temperature measurements system equipped with He3 refrigerator and a 14 Tesla magnet, low temperature ultra-high-vacuum scanning tunneling microscope (UHV-STM). 

    We perform a variety of experiments such as: Magnetotransport, thermal-transport, tunneling and point contact spectroscopy, magnetometry and more. We lean on the fabrication, characterization and electron-microscopy facilities at the Tel Aviv center for nanoscience and nanotechnologies.
    Systems we are currently studying are:

    • Oxide interface based one dimensional quantum wires

    • Two dimensional electron liquid formed at oxide interfaces

    • Topological insulators

    Dr. Moshe Goldstein

    My research involves the theoretical (both analytical and numerical) study of low-dimensional / nanoscale electronic and photonic systems, in and out of equilibrium. Nanoscale systems are immensely important as the basic building blocks of future electronic devices, which may lead, among other potential applications, to the eventual realization of scalable quantum computing. They can be fabricated using a variety of materials, including semiconductor heterostructures, metallic nanowires and nanograins (normal or superconducting), carbon-based materials (graphene, nanotubes, and buckyballs), the recently discovered topological insulators, and even conducting polymers and single molecules. Not less importantly, from a more fundamental perspective, nanoscale systems exhibit a variety of phenomena caused by strong electronic correlations, as well as their interplay with quantum interference effects and nonequilibrium behavior, all of which are central themes in current condensed matter research.

    A Josephson junction is a quantum mechanical device consisting of two superconductors separated by a very thin barrier. In spite of the barrier, and due to quantum mechanics, the superconducting electrons in one superconductor “feel” their neighbors in the other superconductor and “synchronize” with them. This quantum mechanical coherence on a macroscopic scale allows using Josephson junctions as very precise sensors of magnetic fields, e.g., for imaging, or as basic elements for a scalable quantum computer.

    Our research is focused on the fundamental and applied physics of the Josephson effect.

    • Josephson junctions with alternating critical current density, physics of the Josephson effect in grain boundaries in thin films of high-temperature superconductors and superconductor-ferromagnet-superconductor tunnel junctions, splinter vortices carrying nonquantized flux;

    • Nonlocal electrodynamics of Josephson junctions in thin films of high-temperature superconductors, Cherenkov radiation by nonquantized splinter vortices;

    • Coherent emission of terahertz electromagnetic waves from intrinsic Josephson junction stacks in layered high-temperature superconductors in the regime of high-bias current that creates spatial regions with temperature above the critical temperature.

    Our group carries out high energy nuclear physics research, based on a variety of experimental programs at particle accelerators worldwide. We study the structure of nucleons, both individually and as correlated two-nucleon clusters.

    Currently, we run experiments at the Jefferson Laboratory in Newport News, Virginia, the MAMI electron accelerator facility in Mainz, Germany, and the Paul Scherrer Institute  in Zurich, Switzerland.

    Our goal is to solve puzzles and answer fundamental outstanding questions regarding nucleon and nuclear structure. Some of the questions that we are now studying are:

    • How do the strong interactions between quarks/gluons work to form nucleons?

    • To what extent is a nucleon bound inside a nucleus different from a free nucleon?

    • What happens when two nucleons are very close to each other, so that their wave functions strongly overlap?

    • Can cold dense nuclear matter, an important component of neutron stars, be studied at particle accelerator experiments?

    • Do short-range neutron-proton correlations behave very differently from short range neutron-neutron correlations?

    • Can the small concentration of protons inside neutron stars significantly affect the star’s structure?

    • Why does the proton radius measured by electron-proton scattering differ from it’s radius measured by muonic Hydrogen.

    • Dark photon are suggested to exist as heavy gauge bosons that couple weakly to electrons. Can they be found at JLab by electroproduction on a nuclear target?

    Prof. Abner Soffer

    Particle-physics research in recent decades has led to the discovery of the basic constituents of matter and an understanding of the laws of physics that govern the universe. The Large Hadron Collider (LHC), the world’s largest particle accelerator operating near Geneva, has opened a new frontier in this field – the energy frontier.  Research at the LHC has already led to the discovery of what appears like the last missing particle in our current understanding of particle physics – the Higgs boson. But in addition, we expect new particles that indicate yet-unknown forces and physical laws to be produced at the energy regime of the LHC. Prof. Soffer’s research focuses on searches for such particles, in particular particles with long lifetimes, which are predicted by theories related to the dark matter that pervades the universe or to new symmetries of nature. The energies and momenta of the particles produced in high-energy proton-proton collisions are measured by the large particle detector ATLAS, and physicists from around the world analyze the data for signs of new particles and new physical laws.

    An additional frontier in particle-physics research is the intensity frontier, which involves precise measurements of the properties of known particles to search for the effects of new physical laws. Prof. Soffer participates in this research in the BABAR experiment, where he also served as physics analysis coordinator in the years 2011-2012.

    • The main research of Lev Vaidman is in the fields of Foundations of Quantum Mechanics and Quantum Information.

    • Most of his works belong to theoretical physics, but he also performs some experimental work in quantum optics and writes philosophical papers on the many-worlds interpretation of quantum mechanics.

    • His main contributions are variants of quantum measurements: interaction-free measurements (the Elitzur-Vaidman bomb problem), protective measurements, weak measurements (the Aharonov-Albert-Vaidman Effect), non-local measurements (which led to discovery of teleportation of continuous variables).

    • In the area of Quantum Information he invented a secret key distribution with quantum particles in orthogonal states (the Goldenberg-Vaidman protocol), quantum gambling, and practically secure bit commitment.

    • The main tool of his research is the analysis of paradoxes such as the 3-box paradox, the paradox of a photon being at a place through which it cannot pass and more. The Paradoxes help him achieve the goal of deeper understanding of locality and randomness in Nature.

    I am studying the properties of proton-proton interactionsat very high energies up to 13 TeV using the ATLAS detector situated at the Large Hadron Collider at CERN. In particular I am interested in the properties of the Bose-Einsteinand Fermi-Dirac correlation as a function of energy and particle masses. The experimental work is supplement by me by my own phenomenological description on these phenomena. In additionI I am working on plans for
    future electron-positron colliders, like CLIC and the ILC, in particular in relation to the production and measurement of the polarized incoming beams.

    Current research:

    Study of physics beyond the Standard Model through beta decay of trapped nuclei. The atoms are produced by an accelerator and trapped (and if necessary polarized) in a Magneto-Optical trap with laser beams.  The decay products are measured by detectors.


    Prior research:

    Study of the internal structure of the pi meson and the photon by diffractive dissociation to jets that carry information on their internal structure.

    This is an experimental research in high energy physics using the ATLAS detector in the Large Hadron Collider at CERN. The research is focused around the following topics:

    • Precision tests of the Standard Model of elementary particles using events with gauge bosons, such as W, Z and photon.

    • Search for new particles and new phenomena predicted by new models which are beyond the Standard Model
