Comparison of decoherence and Zeno dynamics from the context of weak measurement for a two-level atom traversing through squeezed vacuum

Abstract

Decay parameter of coherence and population inversion are calculated from the master equation of a two-level atom tunneling through a squeezed vacuum. Using those parameters, the timescales for decoherence and Zeno effect are calculated in the weak measurement scheme. By comparing those timescales, a certain condition on the relevant experimental parameters has been found for sustainable coherent dynamics.
