 Anton Andreev  Professor  Condensed Matter Theory  Electron transport in mesoscopic and disordered systems, Coulomb blockade devices, and in other lowdimensional electron systems; theory of speckles of coherent waves propagating through random media. 
  George Bertsch  Emeritus Professor  Manyparticle Theory  I work on applications of timedependent densityfunctional theory to laser and other electromagnetic interactions with condensed matter. Specific topics include dielectric response, dichroism, highfield response, and coherent phonon generation. 
  Marcel den Nijs  Professor  Statistical Physics  Equilibrium and nonequilibrium statistical mechanics and low dimensional quantum field theory, with applications to surface science, one dimensional quantum fluids and solids, and to neuroscience. 


 Lukasz Fidkowski  Assistant Professor  Symmetry and Topology  My research focus is on identifying and classifying exotic phases of matter. In particular, our group focuses on phases which cannot be understood in terms of traditional symmetry breaking GinzburgLandau theory, such as fractional quantum Hall phases and topological insulators (TIs). Recently we have been classifying strongly interacting versions of TIs, termed ‘symmetry protected topological’ phases, using tools such as topological quantum field theory and exactly solved models. We are also interested in other settings for realizing topological order, such as at nonzero energy density or in driven (Floquet) systems, aided by manybody localization. 
  John J. Rehr  Emeritus Professor  FEFF and CMSN  Fundamental condensed matter theory, aiming at a quantitative understanding of electronic structure and manybody theory, using modern high performance computational techniques. 
  Michael Schick  Emeritus Professor  Theory of lipid membranes  Modulated phases of block copolymers and biological lipids; fusion of small vesicles and organization in lipid bilayers, such as the plasma membrane.
