We study the heat current autocorrelation function (HCAF) in one-dimensional, momentum-conserving lattices. In particular, we explore if there is any relation between the decaying characteristics of the HCAF and asymmetric interparticle interactions. The Lennard-Jones model is intensively investigated in view of its significance to applications. It is found that in wide ranges of parameters, the HCAF decays faster than power-law manners, and in some cases it decays even exponentially. Following…

Fourier heat conduction as a strong kinetic effect in one-dimensional hard-core gases.
It is shown that the kinetic effect can be dominant in some cases and leads to the Fourier law for finite-size systems and in a finite range of the system size, whether the system follows the Fouriers law depends on whether the kinetic stage dominates.
The Fourier heat conduction as a strong kinetic effect
For an one-dimensional (1D) momentum conserving system, intensive studies have shown that generally its heat current autocorrelation function (HCAF) tends to decay in a power-law manner and results
Heat conduction in two-dimensional momentum-conserving and -nonconserving gases.
It is found that when the dimensionality of the system is changed from 2D to quasi-one-dimensional (quasi-1D), the heat conductivity diverges with the system size L as κ∼lnL (the theoretical prediction for 2D systems) for a short L and shows a tendency to κ ∼L^{1/3} like that predicted in 1D fluids.
Universal scaling of the thermalization time in one-dimensional lattices.
We show that, in the thermodynamic limit, a one-dimensional (1D) nonlinear lattice can always be thermalized for arbitrarily small nonlinearity, thus proving the equipartition theorem for a class of
Observing golden-mean universality class in the scaling of thermal transport.
Strong evidence is shown that ψ appears to be the scaling exponent of heat mode correlation in a purely quartic anharmonic chain and more ingredients should be taken into account to gain a full prediction of the scaling of thermal transport.
O(N) Fluctuations and Lattice Distortions in 1-Dimensional Systems

Finite-size effects on current correlation functions.
A procedure for correctly evaluating the decay rate of a CCF is proposed, and an analysis suggests that the global energy CCF decays as ∼ t(-2/3) in the diatomic hard-core gas model and in a manner close to ∼ t-1/2 in the Fermi-Pasta-Ulam-β model.

It is found that in the absence of momentum conservation, even ergodicity of an isolated system is not necessary for the normal transport, and the validity of the Fourier law in a pseudo-integrable particle chain is demonstrated.
Numerical test of hydrodynamic fluctuation theory in the Fermi-Pasta-Ulam chain.
This work reports on molecular dynamics simulations of Fermi-Pasta-Ulam chains to compute various spatiotemporal correlation functions and compares them with the predictions of the nonlinear hydrodynamic fluctuation theory, obtaining very good agreement in many cases, but also some deviations.
