Landau-Zener tunneling for dephasing Lindblad evolutions
arXiv:0912.4640
Abstract
We derive an analog of the Landau-Zener adiabatic tunneling formula for an open, two-level system coupled to a memoryless, dephasing bath. The derivation rests on a geometric view of the spectral subspaces as adiabatic invariants.
