Decoherence of a quantum magneto-oscillator: Effect of field-bath interaction
Koushik Mandal, Suraka Bhattacharjee, Supurna Sinha
The paper analyzes how a charged magneto-oscillator coupled to a harmonic heat bath and an additional field-bath interaction loses coherence, showing that the extra coupling speeds…

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…
