Research interests focus on so-called "non-Fermi-liquid behavior'' produced by localized magnetic moments in metals and alloys. Non-Fermi liquids exhibit anomalous physical properties arising from complex interplay between various effects: local interaction of each magnetic moment with its immediate environment, long-range interactions between moments mediated by conduction electrons, and the consequences of lattice order/disorder. Various candidate mechanisms for non-Fermi-liquid behavior are being investigated through theoretical and numerical studies.Selected Publications
