A New Information Soliton to Resist Decaying of the Excitation Based on the External Field Interaction

Abstract

In this work, we reveal possibility using information soliton to resist senescence of certain important bio-excitations (such as Davydov solitons) which play a fundamental role in information processing of life. For this goal, a type of external field interaction with original system is introduced. This field enables the total system to be described by a nonlinear Master equation. Then we found that the nonlinear term in the equation drives the initial excitation to evolve as a kind of information soliton asymptotically. It is this information soliton to resist decaying of the excitations. This provides a constructive way to prolong age of biological excitations by exerting an external field, which forms a basis used in medical devices or treatments.
