Experimental Condensed Matter Physics
Professors Gao & Postma
Dr. Gao is interested in investigating the structural, electronic, magnetic and other properties of low dimensional materials at the atomic or molecular scale by using scanning tunneling microscopy and spectroscopy. His recent research activities focus on the following topics: (1) spin-polarized electron transport through molecules; (2) preparation and atomic-scale characterization of emerging two-dimensional materials; and (3) adsorption, diffusion, reaction and desorption of small molecules on surfaces.
Dr. Postma conducts interdisciplinary research in nanoscience and nanotechnology. He is interested in the properties of materials with intrinsic nanoscale dimensions, such as carbon nanotubes, graphene, nanowires, and DNA. Their small dimensions give rise to interesting effects, such as quantum confinement, and we utilize these for novel applications in computation, sensing, and information storage.
Professors Ranganathan, Peric, & Bezryadina
A state-of-the-art Electron Paramagnetic Resonance (EPR) spectroscopy is combined with the optical technique of Time Resolved Fluorescence Quenching (TRFQ) to investigate certain properties of materials with applications in biology, chemistry and physics.
Dr. Anna Bezryadina interests are in the areas of biophotonics and quantum optics. In particular, she is interested in utilizing optical trapping to manipulate microorganisms, study light-matter interaction, and engineer new generation of biodegradable technology.
Dr. Xu Zhang's research focuses on (1) excited state phenomena for many important energy materials, such as photovoltaics, optoelectronics, solid state lighting and plasmonics, based on developed time dependent density functional theory; (2) stress-controlled catalysis, such as oxygen reduction reaction, hydrogen evolution reaction, and CO2 electroreduction on nanoparticles, nanowires, nanoplates and surface steps using the developed multiscale method.
Professors Chapman & Choudhary
The Department operates the San Fernando Observatory to carry out solar research in which students are involved. The main research goals are (1) the study of magnetic fields and their relation to sunspots and other forms of solar activity, and (2) the study of variations in the output of solar energy and its relation to measurements made in space by spacecrafts observing the Sun.
Theoretical Condensed Matter Physics
Professors Beloborodov & Sheng
Dr. Igor Beloborodov's interests are in the area of theoretical condensed matter physics. In particular, he is interested in the properties of granular electronic systems, nanoscale superconductors and magnets, quantum nanodevices, nanogranular thermoelectrics, spin-based electronics, and strongly correlated electron systems.
Dr. Donna Sheng's research in condensed matter theory involves the Critical behavior in quantum phase transitions in low dimensions, including quantum Hall effect (QHE) systems, spin-orbit coupling systems, random-magnetic-field systems, and the recently experimentally observed metal-insulator transition at zero magnetic field (B=0) in 2D electron systems; (2) Strongly-correlated electron systems, theoretical study of new kind of ordering and Matter of states.
Dr. Kah Chun Lau’s research interests are in the computational materials science. In particular, he is interested in the theoretical model development and materials design of new energy storage and conversion system using advanced atomistic simulation, data mining and machine-learning methods.

Computational Materials Science
The Computational Materials Research Center is housed in the Keck Laboratory. The center operates state-of-the-art computers to calculate intrinsic properties of materials from basic principles. These include mechanical, optical, magnetic, surface properties, and catalysis. Students who get involved with the center get to use sophisticated computers and learn a variety of issues of interest to the field of materials science. Advanced scientific programming, data analysis, and visualization are among several techniques employed at the center. Capabilities exist to help experimental scientists and industrial engineers understand the origin of different materials properties and to design new materials using only computers.
The theoretical group associated with the San Fernando Observatory studies the turbulent processes in the solar atmosphere and the effects of the solar energy variability on the climate of our planet earth. Students have the opportunity to learn analytical and numerical methods and techniques commonly used in analyzing nonlinear dynamical systems and stochastic processes.
Dr. Ren is developing a Universal Adaptive Optics (AO) system for solar telescopes. Compared with other solar AO systems, his system will be able to deliver extremely high Strehl Ratio (i.e. extremely high correction). The well-corrected solar images will be critical for high-sensitivity solar magnetic field investigation, since scattered light induced by the atmosphere turbulence is dramatically reduced; He is also developing a solar Multi-Conjugate AO (MCAO) system, which uses several deformable mirrors to correct the atmosphere turbulence in different altitudes so that a large and uniform corrected field of view is available. Because of the complexity of the MCAO system, currently no MCAO system is available on any astronomical site.
Professor Luchko & Shiferaw
Dr Shiferaw is interested in the application of nonlinear dynamics and pattern formation to problems in biology. Much of my work revolves around the application of these methods to understand the dynamics that underlies abnormal cardiac rhythms which precede a heart attack. This work involves a wide range of scales ranging from the ion channels that regulate the electrical activity in heart cells, to the dynamics of spiral waves in the whole heart.
Dr. Luchko's primary interests are in molecular recognition, the role of water, and in how this can be used to improve computer aided drug discovery. Water and co-solvents are essential factors in molecular recognition. Dr. Luchko's work focuses on improving predictions of the structure and thermodynamics of water and co-solvents around drug-targets, such as proteins and DNA, through the continued development of the 3D reference interaction site model (3D-RISM). His implementation of 3D-RISM is part of the AmberTools molecular modeling suite and can be used for drug discovery and biomolecular simulation in general.
Dr. Christian is an observational stellar and solar astronomer. He is currently working on high cadence, multi-band imaging of the solar atmosphere, measuring abundance trends in extra-solar planet host stars, and optical properties of active cool stars. Dr. Christian is involved with a new high time resolution multi-camera system developed by Queen's University Belfast called ROSA - Rapid Oscillations in the Solar Atmosphere. ROSA was recently commissioned at the Dunn Solar Telescope at the National Solar Observatory in Sunspot, New Mexico, and can obtain over 30 fps in multiple wave-bands to study energy transport in the solar photosphere and chromosphere. Dr. Christian is also continuing work he started with the SuperWASP project's search for planets around other stars (www.superwasp.org) and is investigating abundance trends in planet's host stars that may provide clues into planet formation and evolution.
Dr. Ricci’s primary interests are in exoplanets, protoplanetary disks, formation of young stars and planets. He spends most of his time analyzing data from world-class telescopes which allow us to take close-ups of protoplanetary disks, peering into the dust and gas that forms new worlds. Students have the opportunity to learn some of the state-of-the-art techniques and methods that are commonly used in this field of research.
