Mpemba effect in driven granular gases: role of distance measures
Apurba Biswas, V . V. Prasad, R. Rajesh
Mpemba effect refers to the counterintuitive effect where a system which is initially further from the final steady state equilibrates faster than an identical system that is initi…
Lattice models for ballistic aggregation: cluster-shape dependent exponents
Fahad Puthalath, Apurba Biswas, V. V. Prasad +1
We study ballistic aggregation on a two dimensional square lattice, where particles move ballistically in between momentum and mass conserving coalescing collisions. Three models a…
Mpemba effect in anisotropically driven inelastic Maxwell gases
Apurba Biswas, V. V. Prasad, R. Rajesh
Through an exact analysis, we show the existence of Mpemba effect in an anisotropically driven inelastic Maxwell gas, a simplified model for granular gases, in two dimensions. Mpem…
Mpemba effect in an anisotropically driven granular gas
Apurba Biswas, V. V. Prasad, R. Rajesh
We demonstrate the existence, as well as determine the conditions, of a Mpemba effect - a counterintuitive phenomenon where a hotter system equilibrates faster than a cooler system…
Mpemba effect in driven granular Maxwell gases
Apurba Biswas, V . V. Prasad, O. Raz +1
Mpemba effect refers to the counterintuitive result that, when quenched to a low temperature, a system at higher temperature may equilibrate faster than one at intermediate tempera…
Asymptotic velocity distribution of a driven one dimensional binary granular Maxwell gas
Apurba Biswas, V. V. Prasad, R. Rajesh
We consider the steady states of a driven inelastic Maxwell gas consisting of two types of particles with scalar velocities. Motivated by experiments on bilayers where only one lay…
Ensemble inequivalence in the Blume-Emery-Griffiths model near a fourth order critical point
V. V. Prasad, Alessandro Campa, David Mukamel +1
The canonical phase diagram of the Blume-Emery-Griffiths (BEG) model with infinite-range interactions is known to exhibit a fourth order critical point at some negative value of th…
Landau theory of restart transitions
Arnab Pal, V. V. Prasad
We develop a Landau like theory to characterize the phase transitions in resetting systems. Restart can either accelerate or hinder the completion of a first passage process. The t…
First passage under stochastic resetting in an interval
Arnab Pal, V. V. Prasad
We consider a Brownian particle diffusing in a one dimensional interval with absorbing end points. We study the ramifications when such motion is interrupted and restarted from the…
Velocity distribution of driven granular gases
V. V. Prasad, Dibyendu Das, Sanjib Sabhapandit +1
The granular gas is a paradigm for understanding the effects of inelastic interactions in granular materials. Kinetic theory provides a general theoretical framework for describing…
Asymptotic behavior of the velocity distribution of driven inelastic gas with scalar velocities: analytical results
V. V. Prasad, R. Rajesh
We determine the asymptotic behavior of the tails of the steady state velocity distribution of a homogeneously driven granular gas comprising of particles having a scalar velocity.…
Velocity Distribution of Driven Inelastic One-component Maxwell gas
V. V. Prasad, Dibyendu Das, Sanjib Sabhapandit +1
The nature of the velocity distribution of a driven granular gas, though well studied, is unknown as to whether it is universal or not, and if universal what it is. We determine th…
Driven inelastic Maxwell gas in one dimension
V. V. Prasad, Sanjib Sabhapandit, Abhishek Dhar +1
A lattice version of the driven inelastic Maxwell gas is studied in one dimension with periodic boundary conditions. Each site of the lattice is assigned with a scalar `velocit…
Driven inelastic Maxwell gases
V. V. Prasad, Sanjib Sabhapandit, Abhishek Dhar
We consider the inelastic Maxwell model, which consists of a collection of particles that are characterized by only their velocities, and evolving through binary collisions and ext…
High-Energy Tail of the Velocity Distribution of Driven Inelastic Maxwell Gases
V. V. Prasad, Sanjib Sabhapandit, Abhishek Dhar
A model of homogeneously driven dissipative system, consisting of a collection of particles that are characterized by only their velocities, is considered. Adopting a discrete…
