Research/Areas of Interest: Condensed Matter Physics Research in Condensed Matter Theory has covered many areas, such as off-diagonal long-range order in low dimensional systems - including lattice vibrations, free Fermions and Bosons, superconductivity, magnetism, phase transitions, Mössbauer Effect [alloys, Brownian particles, & ferritin], equilibrium properties exhibited by a pure harmonic lattice, liquid crystals, diffusion in solids via vacancies, solitons, the physics of music and color, and most recently, quantum tunneling of magnetization (QTM).
