The research in the Department of Chemical Physics covers a wide range of interdisciplinary subjects, combining the fields of chemistry, physics and biophysics.

Light-matter interactions (quantum optics) and their applications for quantum information are being investigated theoretically by Gershon Kurizki in periodic structures, cavities, cold atom gases and condensates. A universal strategy, based on electromagnetic pulses, is being developed for effectively combatting decoherence in various quantum systems.

Ilya Averbukh and Yehiam Prior study, both theoretically and experimentally, various aspects of nonlinear optical interactions, including excitation and detection of atomic and molecular wavepackets prepared by shaped femtosecond pulses, nonlinear optical interactions under the tip of a scanning near-field optical microscope, femtosecond laser material processing and molecular alignment and orientation by strong laser fields, atom optics and atom lithography applications.

David J. Tannor is studying, theoretically, femtosecond control of chemical reactions, attosecond control of multielectronic atoms, optimal control of laser cooling, dissipative quantum mechanics and a new formulation of quantum mechanics based on complex trajectories.

The most recent cavity-QED (quantum electodynamics) capabilities with single cold atoms and chip-based microcavities are combined by Barak Dayan to investigate atom-mediated nonlinear photon-photon interactions. These measurements enable the study of single-photon switches, Quantum Non-Demolition (QND) measurements of optical photons and quantum gates.

New and general methods of molecular and atomic cooling are developed by Ed Narevicius. His group is building a magnetic coilgun to decelerate molecular and atomic beams. Cold atoms and molecules will be used to study collisional processes at ultra-low temperatures where quantum effects become dominant.

Ron Naaman is investigating the use of molecules as components in electronic devices and sensors. This includes studying the electronic properties of organized thin molecular films and investigating information transfer through them. The group also studies the interaction of electrons with bio-molecules.

Gilad Haran uses single-molecule fluroescence methods to study conformational dynamics, association and folding of proteins. In addition, his group also uses single-molecule Raman spectroscopy to probe dynamics of individual surface-adsorbed molecules as well as to study plasmonic interactions on the nano-scale.

Single molecule conduction is studied by Oren Tal. Individual molecules are trapped between two metallic electrodes and their electric conductance is measured and related to their structural and dynamic properties. These studies are also an excellent test bed for studying electronic spin transport at the atomic and nanomater scale.

New methods for the computation of real time quantum dynamics in complex systems are developed by Eli Pollak. Applications include ab-initio chemistry, surface scattering, electron transfer, photoinduced processes and more. The fluorescence quenching by electron transfer assisted by diffusion and spin conversion in radical ion pairs as well as for triplet production and annihilation are being studied by Anatoly I. Burshtein within the original integral encounter theory, beyond the rate concept.

Turbulence both in hydrodynamics and in nonlinear wave interactions is investigated by Victor L'vov. Itamar Procaccia's group deals with various phenomena involving complexity in Nature; besides working on turbulence with L'vov, the group studies the properties of amorphous solids. How these solids form via the glass transition and what are the mechanical properties of the resulting amorphous solids, including their modes of failure like fracture, shear banding and plastic flow.

Eran Bouchbinder studies non-equilibrium problems in solid mechanics and materials science, such as breaking and deformation of materials, using tools of statistical and continuum physics while interacting with experimental and computational groups.

Theoretical modeling of cellular shapes and dynamics is studied by Nir Gov. In particular, the unique dynamic features of biological membranes are investigated and a unified model is developed to describe the mechanical properties of the membranes of red-blood cells.

Electron spin resonance (ESR) and double resonance spectroscopic (ENDOR) techniques are developed and applied by Daniella Goldfarb for the characterization of metal active sites in porous inorganic catalysts and metalloenzymes and for the study of the formation mechanism of the mesostructured mesoporus materials. New multidimensional methods of analysis in solution, solid-state and imaging magnetic resonance are also being developed by Lucio Frydman and his group, for the investigation of metabolism, of biomolecular structures and for dynamic elucidations. NMR methodologies are also used by Zeev Luz to investigate ordering and dynamics processes in condensed phases. Recently, Dynamic Nuclear Polarization (DNP) Spectroscopy has been applied to enhance the sensitivity of high resolution NMR spectra and to follow metabolic pathways in biological samples. Basic experimental and theoretical aspects of DNP are also investigated. Water induced molecular motions at solvent-surface interfaces inside mesoporous materials are also studied.
