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…
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…
