Query: Nonlinear dynamics in quantum physics- the study of quantum chaos   We use the quantum action to study the dynamics of quantum system at finite
temperature. We construct the quantum action non-perturbatively and find
temperature dependent action parameters. Here we apply the quantum action to
study quantum chaos. We present a numerical study of a classically chaotic 2-D
Hamiltonian system - harmonic oscillators with anharmonic coupling. We compare
Poincar\'e sections for the quantum action at finite temperature with those of
classical action.
