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…

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…
