Quantum trajectory theory for a two-level atom in a squeezed vacuum field with non-radiative dephasing

Quantum trajectory theory for a two-level atom in a squeezed vacuum field with non-radiative dephasing

The quantum trajectory theory is employed to study the decay of a two-level atom in a partial as well as a pure squeezed vacuum with non-radiative dephasing. We show that ensemble averages taken over a large number of trajectories are in perfect agreement with theoretical results. We find that singl...

description The quantum trajectory theory is employed to study the decay of a two-level atom in a partial as well as a pure squeezed vacuum with non-radiative dephasing. We show that ensemble averages taken over a large number of trajectories are in perfect agreement with theoretical results.
