摘要
We calculate the geometric phase for an atomic qubit coupled to a zero-temperature bosonic reservoir with a Lorentzian spectral density. The geometric phase is obtained without tracing out the degrees of freedom of the reservoir. It is shown that the phase accumulated by the total system is purely geometric and exhibits an oscillation behaviour in both the Markovian and non-Markovian regimes.
