Mixing and Decoherence to Nearest Separable States
Avijit Lahiri, Gautam Ghosh, Sankhasubhra Nag
We consider a class of entangled states of a quantum system (S) and a second system (A) where pure states of the former are correlated with mixed states of the latter, and work out…
Quantum Chaos: Reduced Density Matrix Fluctuations in Coupled Systems
Sankhasubhra Nag, Gautam Ghosh, Avijit Lahiri
Following a recent work (briefly reviewed below) we consider temporal fluctuations in the reduced density matrix elements for a coupled system involving a pair of kicked rotors as…
Entropy production due to coupling to a heat bath in the kicked rotor problem
Sankhasubhra Nag, Avijit Lahiri, Gautam Ghosh
Considering a kicked rotor coupled to a model heat bath both the classical and quantum entropy productions are calculated exactly. Starting with an initial wave packet, the von Neu…
