Soliton Generation in Infinite and Half-Infinite Molecular Chains

Part of the NATO ASI Series book series (NSSB, volume 243)


It is shown that the presence or the absence of a soliton excitation threshold and the threshold values depends on the character of the excitation distribution at the initial time. A study is made of the time evolution of an excitation given at the initial moment as a hyperbolic secant, a rectangular step, and a decreasing exponential, for an infinite chain. A mechanism for generating solitons by exciting the impurity molecules is considered.
