Anomalous Pairing Currents and a Second Topological Edge Channel in Bosonic Lattices
Chitrak Bhadra, Ángel Rivas, Miguel A. Martin-Delgado
We show that bosonic pairing opens a second chiral current channel on a 2D kagome lattice, absent from any particle-conserving model. From the continuity equation, we derive both a…
Controlling the effect of quantum fluctuations in a driven nonlinear parametric oscillator
Somnath Roy, Chitrak Bhadra, Dhrubajyoti Biswas
This study investigates the interplay between a high-frequency external forcing and the intrinsic dynamics of a quantum nonlinear parametric oscillator. To analyze this system, cla…
Quantum Engines and Refrigerators
Loris Maria Cangemi, Chitrak Bhadra, Amikam Levy
Engines are systems and devices that convert one form of energy into another, typically into a more useful form that can perform work. In the classical setup, physical, chemical, a…
Classical Open Systems coupled to Nonlinear Baths: Noise Spectrum and Dynamical Correlations
Chitrak Bhadra, Ion Santra, Dhruba Banerjee
Open system dynamics in a classical setting is microscopically governed by the structure of the thermal environment which influences the dynamics of the probe particle (free or in…
A Strongly Coupled Open System with Non-linear Bath: Fluctuation-Dissipation and Langevin Dynamics
Chitrak Bhadra
Study of Langevin dynamics and the fluctuation-dissipation relation (FDR) for a generic probe system (represented by a mass ), bilinearly coupled to a bath of harmonic oscillato…
System-reservoir theory with anharmonic baths: a perturbative approach
Chitrak Bhadra, Dhruba Banerjee
In this paper we present a study of a general system coupled to a reservoir consisting of nonlinear oscillators, based on perturbation theory at the classical level. We extend the…
Stochastic dynamics of two-step processes with harmonic potential
Jyotipriya Roy, Chitrak Bhadra, Debapriya Das +2
In this paper we address the one-dimensional problem of stochastic renewal in different damping environments. An ensemble of particles with some specified initial distribution in p…
