Interference aided finite resonant response in an undamped forced oscillator
Shihabul Haque, Jayanta K. Bhattacharjee
We apply perturbative techniques to a driven undamped sinusoidal oscillator at resonance. The angular displacement, , obeys the dynamics $\Ddotθ + ω^{2} \sinθ = H\cos{ωt}$. The…
Emergence of a Non-van der Waals Magnetic Phase in a van der Waals Ferromagnet
Bikash Das, Subrata Ghosh, Shamashis Sengupta +12
Manipulation of long-range order in two-dimensional (2D) van der Waals (vdW) magnetic materials (e.g., CrI, CrSiTe etc.), exfoliated in few-atomic layer, can be achieved vi…
Universal scaling regimes in rotating fluid turbulence
Abhik Basu, Jayanta K Bhattacharjee
We analyse the scaling properties of the energy spectra in fully developed incompressible turbulence in forced, rotating fluids in three dimensions (3D), which are believed to be c…
Diagrammatic perturbation theory for Stochastic nonlinear oscillators
Akshay Pal, Jayanta Kumar Bhattacharjee
We consider the stochastically driven one dimensional nonlinear oscillator where f(t) is a Gaussian noise which, for the bulk of the work,…
Perturbation Theory in a Microcanonical Ensemble
Ritapriya Pradhan, Jayanta K. Bhattacharjee
The microcanonical ensemble is a natural starting point of statistical mechanics. However, when it comes to perturbation theory in statistical mechanics, traditionally only the can…
Activity induced turbulence in driven active matter
J. K. Bhattacharjee, T. R. Kirkpatrick
Turbulence in driven stratified active matter is considered. The relevant parameters characterizing the problem are the Reynolds number Re and an active matter Richardson-like numb…
