Dynamics of fluctuation correlation in periodically driven classical system
Aritra Kundu, Atanu Rajak, Tanay Nag
Having established the fact that interacting classical kicked rotor systems exhibit long-lived prethermal phase with quasi-conserved average Hamiltonian before entering into chaoti…
Revisiting the Mazur bound and the Suzuki equality
Abhishek Dhar, Aritra Kundu, Keiji Saito
Among the few known rigorous results for time-dependent equilibrium correlations, important for understanding transport properties, are the Mazur bound and the Suzuki equality. The…
Cosmic recombination history in light of EDGES measurements of the cosmic dawn 21-cm signal
Kanan K. Datta, Aritra Kundu, Ankit Paul +1
The recent EDGES measurements of the global 21-cm signal from the cosmic dawn suggest that the kinetic temperature of the inter-galactic medium (IGM) might be significantly lower c…
Anomalous heat transport in one dimensional systems: a description using non-local fractional-type diffusion equation
Abhishek Dhar, Anupam Kundu, Aritra Kundu
It has been observed in many numerical simulations, experiments and from various theoretical treatments that heat transport in one-dimensional systems of interacting particles cann…
Transport properties of the classical Toda chain: effect of a pinning potential
Abhishek Dhar, Aritra Kundu, Joel L. Lebowitz +1
We consider energy transport in the classical Toda chain in the presence of an additional pinning potential. The pinning potential is expected to destroy the integrability of the s…
Fractional diffusion equation description of an open anomalous heat conduction set-up
Aritra Kundu, Cédric Bernardin, Keji Saito +2
We provide a stochastic fractional diffusion equation description of energy transport through a finite one-dimensional chain of harmonic oscillators with stochastic momentum exchan…
