Decoherence of a quantum magneto-oscillator: Effect of field-bath interaction
Koushik Mandal, Suraka Bhattacharjee, Supurna Sinha
We investigate the quantum dissipative dynamics of a charged magneto-oscillator(CMO) coupled to a heat bath of harmonic oscillators in the presence of an additional field-bath inte…
Decoherence of a dissipative Brownian charged magneto-anharmonic oscillator: an information theoretic approach
Suraka Bhattacharjee, Koushik Mandal, Supurna Sinha
We study the decoherence of an anisotropic anharmonic oscillator in a magnetic field, coupled to a bath of harmonic oscillators at high and low temperatures. We solve the anharmoni…
Non-resonant inter-species interaction and its effect on the position response function of cold atoms
Anirban Misra, Urbashi Satpathi, Supurna Sinha +2
In the context of non-equilibrium statistical physics, the position response of a particle, coupled to a bath, subjected to an external force is a topic of broad interest. A topic…
Decoherence of a charged Brownian particle in a magnetic field : an analysis of the roles of coupling via position and momentum variables
Suraka Bhattacharjee, Koushik Mandal, Supurna Sinha
The study of decoherence plays a key role in our understanding of the transition from the quantum to the classical world. Typically, one considers a system coupled to an external b…
Effect of light-assisted tunable interaction on the position response function of cold atoms
Anirban Misra, Urbashi Satpathi, Supurna Sinha +2
The position response of a particle subjected to a perturbation is of general interest in physics. We study the modification of the position response function of an ensemble of col…
Decoherence and the ultraviolet cutoff: non-Markovian dynamics of a charged particle in a magnetic field
Suraka Bhattacharjee, Koushik Mandal, Supurna Sinha
We derive a non-Markovian master equation for a charged particle in a magnetic field coupled to a bath and study decoherence by analysing the temporal decay of the off-diagonal ele…
