The Taylor-von Neumann-Sedov blast-wave solution: comparisons with microscopic simulations of a one-dimensional gas
Santhosh Ganapa, Subhadip Chakraborti, P. L. Krapivsky +1
We study the response of an infinite system of point particles on the line initially at rest on the instantaneous release of energy in a localized region. We make a detailed compar…
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…
Microscopic theory of the fluctuating hydrodynamics in nonlinear lattices
Keiji Saito, Masaru Hongo, Abhishek Dhar +1
The theory of fluctuating hydrodynamics has been an important tool for analyzing macroscopic behavior in nonlinear lattices. However, despite its practical success, its microscopic…
Quantum Brownian Motion: Drude and Ohmic Baths as Continuum Limits of the Rubin Model
Avijit Das, Abhishek Dhar, Ion Santra +2
The motion of a free quantum particle in a thermal environment is usually described by the quantum Langevin equation, where the effect of the bath is encoded through a dissipative…
Active Brownian particle in harmonic trap: exact computation of moments, and re-entrant transition
Debasish Chaudhuri, Abhishek Dhar
We consider an active Brownian particle in a -dimensional harmonic trap, in the presence of translational diffusion. While the Fokker-Planck equation can not in general be solve…
Universal scaling in active single-file dynamics
Pritha Dolai, Arghya Das, Anupam Kundu +3
We study the single-file dynamics of three classes of active particles: run-and-tumble particles, active Brownian particles and active Ornstein-Uhlenbeck particles. At high activit…
