Unified Approach to Crossover Phenomena
arXiv:cond-mat/9810046 · doi:10.1103/PhysRevE.58.4197
Abstract
A general analytical method is developed for describing crossover phenomena of arbitrary nature. The method is based on the algebraic self-similar renormalization of asymptotic series, with control functions defined by crossover conditions. The method can be employed for such difficult problems for which only a few terms of asymptotic expansions are available, and no other techniques are applicable. As an illustration, analytical solutions for several important physical problems are presented.
