Construction of exact solutions of Bloch-Maxwell equation based on Darboux transformation

摘要

A new strategy, using Darboux transformations, of finding self-switchingsolutions of $i\dot{\rho} = [H, f({\rho})]$ is introduced. Unlike the previousones, working for any f but for Hamiltonians whose spectrum contains at leastthree equally spaced eigenvalues, the strategy does not impose any restrictionon the discrete part of the spectrum of H. The strategy is applied to theBloch-Maxwell system.
