Dissipative Quantum Systems and the Heat Capacity Enigma
S. Dattagupta, Jishad Kumar, S. Sinha +1
We present a detailed study of the quantum dissipative dynamics of a charged particle in a magnetic field. Our focus of attention is the effect of dissipation on the low- and high-…
Dissipative dynamics of a Harmonic Oscillator : A non-perturbative approach
Jishad Kumar, S. Sinha, P. A. Sreeram
Starting from a microscopic theory, we derive a master equation for a harmonic oscillator coupled to a bath of non-interacting oscillators. We follow a non-perturbative approach, p…
Low temperature Thermodynamics in the Context of Dissipative Diamagnetism
Jishad Kumar, P. A. Sreeram, Sushanta Dattagupta
We revisit here the effect of quantum dissipation on the much - studied problem of Landau diamagnetism, and analyze the results in the light of the third law of thermodynamics. The…
