Andrew Millis is a theoretical physicist whose primary research interests include theoretical condensed matter physics.
He is especially interested in the relationship of theories of strongly correlated electrons in solids and of quantum transitions to the behaviour of novel materials, including high temperature superconductors, ‘colossal’ magnetoresistance manganites, quasi-one-dimensional conductors, heavy fermion systems and nearly magnetic systems.
Other research interests: optical conductivity as a probe of correlated electron physics; the physics governing magnetic transition temperatures in ‘half metals’; superconductivity near quantum critical points; electron-phonon coupling in correlated electron systems; effects of disorder on correlated electron and quantum critical materials; phase fluctuations and the theory of the ‘pseudogap’ in high temperature superconductors; interplay between local electronic physics and strain fields; the relation of Luttinger liquid physics to experiments on quantum wires; nonequilibrium behaviour of correlated systems; and the theory of magnetic semiconductors.
