Thermal conductivity of a classical one-dimensional spin-phonon system
Thermal conductivity of a classical one-dimensional spin-phonon system
We investigate the thermal conduction properties of a one-dimensional lattice of atoms carrying classical spins and coupled vibrationally. The spin degrees of freedom interact via a classical Heisenberg interaction, while the vibrational degrees of freedom are coupled through nearest-neighbor linear as well as nonlinear forces. The thermal conductivity in spin-phonon …
