Abstract:

The electronic interactions responsible for the observed electronically induced phase transformations in several important classes of materials are being investigated theoretically in close collaboration with experimental programs at other institutions. These include destruction of superconductivity and onset of a normal magnetic state at low temperatures in ternary rare-earth superconducting compounds, charge density waves in layered transition metal dichalcogenides, origin of phonon anomalies in Pd and Pt metals, local density formalism for electronic bands, and metal-insulator phase transition in Nb02.
