Asymptotic Theory of Self-Trapping of Heat Pulses in Solids

Abstract

Using an asymptotic analysis leading to a modified Korteweg-de Vries equation and a nonlinear parabolic equation, it is shown that under certain conditions on phonon dispersion and lattice anharmonicity, self-trapping of heat pulses occurs in solids at low temperatures.
