Geometric phase for an adiabatically evolving open quantum system
Geometric phase for an adiabatically evolving open quantum system
We derive a solution for a two-level system evolving adiabatically under the influence of a driving field, which includes open system effects. This solution, which is obtained by working in the representation corresponding to the eigenstates of the time-dependent Hermitian Hamiltonian, enables the dynamic and geometric phases of the evolving …
