Thermalization and hydrodynamics in an interacting integrable system: the case of hard rods
Sahil Kumar Singh, Abhishek Dhar, Herbert Spohn +1
We consider the relaxation of an initial non-equilibrium state in a one-dimensional fluid of hard rods. Since it is an interacting integrable system, we expect it to reach the Gene…
Observation of multiple attractors and diffusive transport in a periodically driven Klein-Gordon chain
Umesh Kumar, Seemant Mishra, Anupam Kundu +1
We consider a Klein-Gordon chain that is periodically driven at one end and has dissipation at one or both boundaries. An interesting numerical observation in a recent study~[arXiv…
Crossover in densities of confined particles with finite range of interaction
Saikat Santra, Anupam Kundu
We study a one-dimensional classical system of particles confined within a harmonic trap. Interactions among these particles are dictated by a pairwise potential , where…
Search with stochastic home-returns can expedite classical first passage under resetting
Arup Biswas, Anupam Kundu, Arnab Pal
Classical first passage under resetting is a paradigm in the search process. Despite its multitude of applications across interdisciplinary sciences, experimental realizations of s…
Tracer dynamics in the active random average process
Saikat Santra, Prashant Singh, Anupam Kundu
We investigate the dynamics of tracer particles in the random average process (RAP), a single-file system in one dimension. In addition to the position, every particle possesses an…
Unusual ergodic and chaotic properties of trapped hard rods
Debarshee Bagchi, Jitendra Kethepalli, Vir B. Bulchandani +4
We investigate ergodicity, chaos and thermalization for a one-dimensional classical gas of hard rods confined to an external quadratic or quartic trap, which breaks microscopic int…
