Microscopic analysis of relaxation behavior in nonlinear optical conductivity of graphene
Bristi Ghosh, Sushanta Dattagupta, Malay Bandyopadhyay
We present here a general formulation for the interband dynamical optical conductivity in the nonlinear regime of graphene in the presence of a quantum bath comprising phonons and…
Independent-oscillator model and the quantum Langevin equation for an oscillator: A review
Aritra Ghosh, Malay Bandyopadhyay, Sushanta Dattagupta +1
This review provides a brief and quick introduction to the quantum Langevin equation for an oscillator, while focusing on the steady-state thermodynamic aspects. A derivation of th…
Quantum coherent control of nonlinear thermoelectric transport in a triple-dot Aharonov-Bohm heat engine
Jayasmita Behera, Salil Bedkihal, Bijay Kumar Agarwalla +1
We investigate the role of quantum coherence and higher harmonics resulting from multiple-path interference in nonlinear thermoelectricity in a two-terminal triangular triple-dot A…
Quantum dissipation and the virial theorem
Aritra Ghosh, Malay Bandyopadhyay
In this note, we study the celebrated virial theorem for dissipative systems, both classical and quantum. The classical formulation is discussed and an intriguing effect of the ran…
Partition of kinetic energy and magnetic moment in dissipative diamagnetism
Jasleen Kaur, Aritra Ghosh, Malay Bandyopadhyay
In this paper, we analyze dissipative diamagnetism, arising due to dissipative cyclotron motion in two dimensions, in the light of the quantum counterpart of energy equipartition t…
Partition of free energy for a Brownian quantum oscillator: Effect of dissipation and magnetic field
Jasleen Kaur, Aritra Ghosh, Malay Bandyopadhyay
Recently, the quantum counterpart of energy equipartition theorem has drawn considerable attention. Motivated by this, we formulate and investigate an analogous statement for the f…
