Web15 de ago. de 2016 · Download PDF Abstract: Motivated by correlated decay processes producing gain, loss and lasing in driven semiconductor quantum-dots, we develop a theoretical technique using Keldysh diagrammatic perturbation theory to derive a Lindblad master equation that goes beyond the usual second order perturbation theory. We … WebPerturbation theory can be used to solve nontrivial differential-equation problems. Consider, for example, the Schrödinger equation initial-value problem (10) where Q (x) is an arbitrary continuous function of x. This is a hard problem because there is no quadrature solution for a Schrödinger equation.
