Journal ArticleDOI
Thermal conduction in classical low-dimensional lattices
TL;DR: In this paper, the authors consider stationary energy transport in crystals with reference to simple mathematical models consisting of coupled oscillators on a lattice, and the role of lattice dimensionality on the breakdown of the Fourier's law is discussed.
Journal ArticleDOI
Heat Conduction in Chains of Nonlinear Oscillators
TL;DR: In this paper, heat conduction in chains of nonlinear oscillators with time-reversible thermostats is studied and a nontrivial temperature profile is found to set in, which obeys a simple scaling relation for increasing the number of particles.
Journal ArticleDOI
On the anomalous thermal conductivity of one-dimensional lattices
TL;DR: In this paper, the divergence of the thermal conductivity in the thermodynamic limit is thoroughly investigated and the divergence law is consistently determined with two different numerical approaches based on equilibrium and nonequilibrium simulations, and a possible explanation in the framework of linear response theory is also presented, which traces back the physical origin of this anomaly to the slow diffusion of the energy of long-wavelength Fourier modes.
Journal ArticleDOI
Asymmetric wave propagation in nonlinear systems.
TL;DR: A class of exact extended solutions is constructed such that waves with the same frequency and incident amplitude impinging from left and right directions have very different transmission coefficients.
