Heat transport in low-dimensional systems

A Dhar - Advances in Physics, 2008 - Taylor & Francis
Recent results on theoretical studies of heat conduction in low-dimensional systems are
presented. These studies are on simple, yet non-trivial, models. Most of these are classical …

Anomalous heat transport in one dimensional systems: a description using non-local fractional-type diffusion equation

A Dhar, A Kundu, A Kundu - Frontiers in Physics, 2019 - frontiersin.org
It has been observed in many numerical simulations, experiments and from various
theoretical treatments that heat transport in one-dimensional systems of interacting particles …

Superdiffusion of energy in a chain of harmonic oscillators with noise

M Jara, T Komorowski, S Olla - Communications in Mathematical Physics, 2015 - Springer
We consider a one dimensional infinite chain of harmonic oscillators whose dynamics is
perturbed by a stochastic term conserving energy and momentum. We prove that in the …

Nonequilibrium stationary state of a harmonic crystal with alternating masses

V Kannan, A Dhar, JL Lebowitz - … Review E—Statistical, Nonlinear, and Soft …, 2012 - APS
We analyze the nonequilibrium steady states (NESS) of a one-dimensional harmonic chain
of N atoms with alternating masses connected to heat reservoirs at unequal temperatures …

Characterization of a class of weak transport-entropy inequalities on the line

N Gozlan, C Roberto, PM Samson, Y Shu, P Tetali - 2018 - projecteuclid.org
We study an weak transport cost related to the notion of convex order between probability
measures. On the real line, we show that this weak transport cost is reached for a coupling …

Energy transport in stochastically perturbed lattice dynamics

G Basile, S Olla, H Spohn - Archive for rational mechanics and analysis, 2010 - Springer
We consider lattice dynamics with a small stochastic perturbation of order ε and prove that
for a space–time scale of order ε^-1 the local spectral density (Wigner function) evolves …

Integrable heat conduction model

C Franceschini, R Frassek, C Giardinà - Journal of Mathematical …, 2023 - pubs.aip.org
We consider a stochastic process of heat conduction where energy is redistributed along a
chain between nearest neighbor sites via an improper beta distribution. Similar to the well …

Energy current correlation in solvable long-range interacting systems

S Tamaki, K Saito - Physical Review E, 2020 - APS
We consider heat transfer in one-dimensional systems with long-range interactions. It is
known that typical short-range interacting systems shows anomalous behavior in heat …

Role of the range of the interactions in thermal conduction

C Olivares, C Anteneodo - Physical Review E, 2016 - APS
We investigate thermal transport along a one-dimensional lattice of classical inertial rotators,
with attractive couplings that decrease with distance as r− α (α≥ 0), subject at its ends to …
