Quantum irreversibility and noise in mesoscopic devices

Mostrar todas las versiones(3)

Irreversibility in quantum processes in the Bunimovich stadium and rectangular billiard in the presence of noise is studied. For this purpose, a novel method based on Loschmidt echo and quantum trajectories, as defined in the de Broglie-Bohm formulation, is used. Our results indicate that the dynami...
