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…
