Geometric phase accumulated in a driven quantum system coupled to an structured environment
arXiv:1912.02697 · doi:10.1103/PhysRevA.101.052112
Abstract
We study the role of driving in a two-level system evolving under the presence of a structured environment. We find that adding a periodical modulation to the two-level system can greatly enhance the survival of the geometric phase for many time periods. We show that this effect is mainly important for a markovian regimen but can still be found when the environment exhibits non-markovian behavior as time revivals. This knowledge can aid the search for physical set-ups that best retain quantum properties under dissipative dynamics.
