Phys. Rev. Lett. 105, 030401 (2010) [4 pages]Decoherence in Adiabatic Quantum Evolution: Application to Cooper Pair PumpingReceived 19 November 2009; revised 3 May 2010; published 12 July 2010 One of the challenges of adiabatic control theory is the proper inclusion of the effects of dissipation. Here we study the adiabatic dynamics of an open two-level quantum system deriving a generalized master equation to consistently account for the combined action of the driving and dissipation. We demonstrate that in the zero-temperature limit the ground state dynamics is not affected by environment. As an example, we apply our theory to Cooper pair pumping, which demonstrates the robustness of ground state adiabatic evolution. © 2010 The American Physical Society URL:
