Subharmonic entrainment and limit cycle modulation by high frequency excitation: A Renormalization group approach
Somnath Roy, Debapriya Das, Dhruba Banerjee
In this article, we explore the possibility of a sub-harmonic entrainment and supercritical Hopf bifurcation in a van der Pol-Duffing oscillator that has been excited by…
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…
Generating a perfect quantum optical vortex
Anindya Banerji, Ravindra Pratap Singh, Dhruba Banerjee +1
In this article we introduce a novel quantum state, the perfect quantum optical vortex state which exhibits a highly localised distribution along a ring in the quadrature space. We…
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…
Entanglement propagation of a quantum optical vortex state
Anindya Banerji, Ravindra Pratap Singh, Dhruba Banerjee +1
We study the entanglement evolution of a quantum optical vortex state propagating through coupled lossless waveguides. We consider states generated by coupling two squeezed modes u…
