  • Random Matrix Theory, Quantum Chaos

We study the statistical properties of energy levels and states of different model Hamiltonians and physical systems. From the energy levels, we identify the integrable-chaos transition by studying short-range correlations. Also from the long-range energy correlations we identify critical energy scales, e.g. Thouless energy, Heisenberg energy. For the energy states, we identify the critical points where localization-delocalization transition happens and ergodicity breaks down and quantify the scaling of relevant fluctuations. We also study thermalization and dynamical aspects of a quantum mechanical system.
