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…

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…
