Abstract :We report the results of an investigation of the effects of non-Markovian corrections to the dynamics of two-time correlation functions of the strong interaction spin-boson model. Beyond quantum regression theorem corrections are taken into account at the low environmental temperatures for a two-level system insert ignore into journalissuearticles values(TLS); which is in contact with a structured bath. The results indicate that the corrections lead to appreciable insert ignore into journalissuearticles values(small); quantitative insert ignore into journalissuearticles values(qualitative); differences for both biased and non-biased TLS settings.
Keywords : Quantum regression theorem, open quantum systems, spin boson model, quantum dynamics, two time correlation functions
