Title: | Temperature dependence of thermal conductivity in 1D nonlinear lattices | Authors: | Li, N. Li, B. |
Issue Date: | 1-May-2007 | Citation: | Li, N., Li, B. (2007-05-01). Temperature dependence of thermal conductivity in 1D nonlinear lattices. EPL 78 (3) : -. ScholarBank@NUS Repository. https://doi.org/10.1209/0295-5075/78/34001 | Abstract: | We examine the temperature dependence of thermal conductivity of one-dimensional nonlinear (anharmonic) lattices with and without on-site potential. It is found from computer simulation that the heat conductivity depends on temperature via the strength of nonlinearity. Based on this correlation, we make a conjecture in the effective phonon theory that the mean-free-path of the effective phonon is inversely proportional to the strength of nonlinearity. We demonstrate analytically and numerically that the temperature behavior of the heat conductivity κ 1/T is not universal for 1D harmonic lattices with a small nonlinear perturbation. The computer simulations of temperature dependence of heat conductivity in general 1D nonlinear lattices are in good agreement with our theoretic predictions. Possible experimental tests are discussed. © Europhysics Letters Association. | Source Title: | EPL | URI: | http://scholarbank.nus.edu.sg/handle/10635/98223 | ISSN: | 02955075 | DOI: | 10.1209/0295-5075/78/34001 |
