Andrey V. Chubukov
Andrey Chubukov received his Ph.D. in 1985 from Moscow State University and is currently Professor of Physics at the University of Wisconsin-Madison. His research interests are in theoretical condensed matter physics and include the interplay between magnetism and superconductivity in cuprates and iron pnictides, Fermi liquid theory, quantum critical behavior, and frustrated magnetism. He is a fellow of the APS.
High-resolution angle-dependent quantum oscillations in underdoped cuprates and unrestricted fits are used to suggest a new Fermi surface topology.
New theoretical work shows that in two-dimensional condensed matter systems, one-dimensional processes such as forward or backward scattering have a dramatic effect on the physical behavior of fermions near a quantum critical point and derail attempts to get an accurate description of a non-Fermi-liquid.
