Noise-induced transition in a quantum system
Pulak Kumar Ghosh, Debashis Barik, Deb Shankar Ray
We examine the noise-induced transition in a fluctuating bistable potential of a driven quantum system in thermal equilibrium. Making use of a Wigner canonical thermal distribution…
Quantum state-dependent diffusion and multiplicative noise: a microscopic approach
Debashis Barik, Deb Shankar Ray
The state-dependent diffusion, which concerns the Brownian motion of a particle in inhomogeneous media has been described phenomenologically in a number of ways. Based on a system-…
Noise-induced quantum transport
Pulak Kumar Ghosh, Debashis Barik, Deb Shankar Ray
We analyze the problem of directed quantum transport induced by external exponentially correlated telegraphic noise. In addition to quantum nature of the heat bath, nonlinearity of…
