A deterministic Wigner approach for superposed states

Johann Cervenka, Robert Kosik, Mihail Nedjalkov

Abstract The Wigner formalism is a convenient way of describing quantum mechanical effects through a framework of distribution functions in phase space. Currently, there are stochastic and deterministic approaches in use. In our deterministic method, the critical discretization of the diffusion term is done through the utilization of an integral formulation of the Wigner equation. This deterministic method is studied in the context of superposed quantum states as a precursor to simulations of entangled states.

Wigner Monte Carlo simulation without discretization error of the tunneling rectangular barrier

Orazio Muscato, Vincenza Di Stefano

Abstract The Wigner transport equation can be solved stochastically by Monte Carlo techniques based on the theory of piecewise deterministic Markov processes. A new stochastic algorithm, without time discretization error, has been implemented and studied in the case of the quantum transport through a rectangular potential barrier.

Deterministic Chaos And Noise In Optical Bistability

R. Neumann

The time-dependent solutions of the mean-field Maxwell-Bloch equations for optical bistability are studied numerically for the deterministic equations and the stochastic equations with additional noise sources. From the solution of the deterministic equations a discrete, one-dimensional return map is constructed which proves the existence of deterministic chaos and shows that the Feigenbaum scenarium is valid. Inclusion of noise sources leads to destabilization of higher periodic solutions.
