The main areas of his current research are
- Theory of exchange coupling and giant magnetoresistance in magnetic multilayers.
- Theory of strongly correlated systems including heavy fermions and high temperature superconductivity.
His research in condensed matter theory over the past fifty years is described in about 140 papers (the most recent appear in Publications on this web page) on the following topics:
Itinerant electron magnetism; chemisorption; strongly correlated electron systems including heavy fermions, high temperature superconductors and the Mott transition; spin waves in metals and alloys; surface magnetism; exchange coupling, magnetocrystalline anisotropy, giant magnetoresistance and current-induced switching of magnetization in magnetic multilayers ; metamagnetic transitions; density functional theory; quantum phase transitions.
