Entanglement in bipartite systems with a mixed phase space — •Maximilian Kieler1 and Arnd Bäcker1,2 — 1TU Dresden, Institut für Theoretische Physik, Dresden — 2MPI für Physik komplexer Systeme, Dresden
The entanglement of pure states in a bipartite system can be characterized by the von Neumann entropy. We consider the case of two coupled quantized standard maps, where one map is chosen to be integrable while the other is fully chaotic. By increasing the coupling a transition to nearly maximal entanglement is found. We investigate the implications of the integrable part on the transition of the spectral statistics and the von Neumann entropy. The analytical description will be based on a suitable random matrix model and the identification of the relevant transition parameter.
