Heat conduction in deformable Frenkel-Kontorova lattices: thermal conductivity and negative differential thermal resistance [PDF]
Phys. Rev. E 83 (2011)011131, 2011 Heat conduction through the Frenkel-Kontorova (FK) lattices is numerically investigated in the presence of a deformable substrate potential. It is found that the deformation of the substrate potential has a strong influence on heat conduction. The thermal conductivity as a function of the shape parameter is nonmonotonic.

Thermal Conduction and Multiphase Gas in Cluster Cores [PDF]
, 2013 We examine the role of thermal conduction and magnetic fields in cores of galaxy clusters through global simulations of the intracluster medium (ICM). In particular, we study the influence of thermal conduction, both isotropic and anisotropic, on the condensation of multiphase gas in cluster cores. Previous hydrodynamic simulations have shown that cold

Simulating Anisotropic Thermal Conduction in Supernova Remnants I : Numerics and the Evolution of Remnants [PDF]
arXiv, 2006 Anisotropic thermal conduction plays an important role in various astrophysical systems. One of the most stringent tests of thermal conduction can be found in supernova remnants. In this paper we study anisotropic thermal conduction and examine the physical nature of the flux of thermal conduction in the classical and saturated limits.

Chaos and thermal conductivity [PDF]
Physical Review E, 1995 We argue that the condition of local thermal equilibrium realized several years ago by Rich and Visscher [Phys. Rev. B 11, 2164 (1975)] through a process of mathematical convergence can be obtained dynamically by adopting the prescription of a recent paper [M. Bianucci, R. Mannella, B. J. West, and P. Grigolini, Phys. Rev. E 51, 3002 (1995)].

Thermal conductivity of micro/nano-porous polymers: Prediction models and applications [PDF]
Front. Phys. 17(2), 23202 (2022), 2021 Micro/nano porous polymeric material is considered a unique industrial material due to its extremely low thermal conductivity, low density, and high surface area. Therefore, it is necessary to establish an accurate thermal conductivity prediction model suiting their applicable conditions and provide a theoretical basis for expanding of their ...
