Dissipative tunneling in presence of classical chaos in a mixed quantum-classical system
Bidhan Chandra Bag, Bikash Chandra Gupta, Debshankar Ray
We consider the tunneling of a wave packet through a potential barrier which is coupled to a nonintegrable classical system and study the interplay of classical chaos and dissipati…
Quantum noise-induced chaotic oscillations
Bidhan Chandra Bag, Deb Shankar Ray
We examine the weak quantum noise limit of Wigner equation for phase space distribution functions. It has been shown that the leading order quantum noise described in terms of an a…
Chaos and information entropy production
Bidhan Chandra Bag, Jyotipratim Ray Chaudhuri, Deb Shankar Ray
We consider a general N-degree-of-freedom nonlinear Hamiltonian system which is chaotic and dissipative and show that the origin of chaotic diffusion lies in the correlation of flu…
A semiclassical theory of dissipative Henon-Heiles system
Bidhan Chandra Bag, Deb Shankar Ray
A semiclassical theory of dissipative Henon-Heiles system is proposed. Based on -scaling of an equation for evolution of Wigner quasiprobability distribution function in pre…
A semiclassical theory of quantum noise in open chaotic systems
B. C. Bag, S. Chaudhuri, J. Ray Chaudhuri +1
We consider the quantum evolution of classically chaotic systems in contact with surroundings. Based on -scaling of an equation for time evolution of the Wigner's quasi-prob…
