Nucleation of superconductivity under rapid cycling of electric field

Malay Bandyopadhyay

The effect of an externally applied high frequency oscillating electric field on the critical nucleation field of superconductivity in the bulk as well as at the surface of a super…

Dissipative diamagnetism with anomalous coupling and third law

Malay Bandyopadhyay, Sushanta Dattagupta

In this work, low temperature thermodynamic behaviour in the context of dissipative diamagnetism with anomalous coupling is analyzed. We find that finite dissipation substitutes th…

Charged oscillator in a heat bath in the presence of a magnetic field & third law of thermodynamics

Malay Bandyopadhyay

The quantum thermodynamic behaviour of a charged oscillator in the presence of a magnetic field and coupled to a heat bath through different coupling schemes is obtained analytical…

Memory in nanomagnetic systems: Superparamagnetism versus Spinglass behavior

Malay Bandyopadhyay, Sushanta Dattagupta

The slow dynamics and concomitant memory (aging) effects seen in nanomagnetic systems are analyzed on the basis of two separate paradigms : superparamagnets and spinglasses. It is…

Landau-Drude Diamagnetism: Fluctuation, Dissipation and Decoherence

Malay Bandyopadhyay, Sushanta Dattagupta

Starting from a quantum Langevin equation (QLE) of a charged particle coupled to a heat bath in the presence of an external magnetic field, we present a fully dynamical calculation…

Diffusion Enhancement in a Periodic Potential under High-Frequency Space-Dependent Forcing

Malay Bandyopadhyay, Sushanta Dattagupta, Monamie Sanyal

We study the long-time behavior of underdamped Brownian particle moving through a viscous medium and in a systematic potential, when it is subjected to a space-dependent high-frequ…
