Comparison of decoherence and Zeno dynamics from the context of weak   measurement for a two level atom tunneling through squeezed vacuum
  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 has been found for sustainable coherent dynamics.
