Non-local linear response in anomalous transport
Anupam Kundu
Anomalous heat transport observed in low dimensional classical systems is associated to super-diffusive spreading of space-time correlation of the conserved fields in the system. T…
Boltzmann's entropy during free expansion of an interacting ideal gas
Subhadip Chakraborti, Abhishek Dhar, Anupam Kundu
In this work we study the evolution of Boltzmann's entropy in the context of free expansion of a one dimensional interacting gas inside a box. Boltzmann's entropy is defined for si…
Finite temperature equilibrium density profiles of integrable systems in confining potentials
Jitendra Kethepalli, Debarshee Bagchi, Abhishek Dhar +2
We study the equilibrium density profile of particles in two one-dimensional classical integrable models, namely hard rods and the hyperbolic Calogero model, placed in confining po…
Filling an empty lattice by local injection of quantum particles
Akash Trivedi, Bijay Kumar Agarwalla, Abhishek Dhar +3
We study the quantum dynamics of filling an empty lattice of size , by connecting it locally with an equilibrium thermal bath that injects non-interacting bosons or fermions. We…
Super-diffusion and crossover from diffusive to anomalous transport in a one-dimensional system
Anupam Kundu
We study transport in a one-dimensional lattice system with two conserved quantities -- `volume' and energy. Considering a slowly evolving local equilibrium state that is slightly…
Mass fluctuations in Random Average Transfer Process in open set-up
Rahul Dandekar, Anupam Kundu
We define a new mass transport model on a one-dimensional lattice of size with continuous masses at each site. The lattice is connected to mass reservoirs of different `chemica…
