Condensed Matter & Material Physics: Theory

Our group’s research currently focuses on exploring electron and phonon transport, along with their coupled interaction, in novel materials and devices using first-principles quantum transport theory. In particular, we investigate aspects of emerging nanoelectronics, thermoelectric conversion as well as fundamental issues in nonequilibrium electro-thermal transport at the nanoscale

Dr. Andrew Rutenberg's research group investigates the biological structures of bacteria, which are self-assembled and dynamic. This are of research is a rich field at the overlap of molecular biology and condensed-matter physics.

Dr. Rutenberg's broader interest is in non-equilibrium structure formation; more specifically, he finds bacteria interesting as they have a mature nanotechnology. Dr. Rutenberg's group explores how bacteria's subcellular mechanisms function despite the large noise inherent in their small size. The group models spatial and temporal patterns within bacteria, using the techniques of statistical, computational, and theoretical physics.

We are a multidisciplinary computational group that spans Physics, Chemistry (pH) and Materials Science. Research in my group focuses on understanding kinetic processes dictating the performance and durability of batteries and catalysts from first principles. These materials are constantly operated under non-equilibrium conditions and always contain various defects. To improve energy efficiency and lifetime of a device, it is necessary to understand ion diffusion and reaction coupled with the evolution of defects in materials. Our simulations will unveil factors affecting materials performances with atomistic details that are not easily accessible experimentally. Ultimately, our goal is to guide the atomistic-level control of materials for a sustainable future. See Dr. Xiao's profile page for more information
