DEPARTMENT OF PHYSICS AND ASTRONOMY

 Anupam Garg is interested in the formalism and applications of coherent state path integrals, especially as they relate to spin angular momentum and molecular magnets. He also maintains a cultural interest in the foundations of quantum mechanics, and is the co-discoverer of the Leggett-Garg inequality. His recent interests include phonon scattering from grain boundaries; micromagnetic simulations of ferromagnetic resonance and nonlinear large angle dynamics; and topological quenching of tunneling in molecular magnets and the associated diabolical points in their energy spectra.
