Abstract
A perturbation approach is adopted to solve the model Bloch equations
for a 2-level atom in an off-resonant squeezed vacuum (SV) with an
exponentially decaying driving field up to the second order in the Rabi
frequency of the driving field. Both the instantaneous mean atomic variables
(population, polarization) and the Boltzmann-Gibbs (BG) atomic
entropy are calculated. Effect of the SV parameters and the damping
rate of the driving field are examined computationally. Entropy investigation
shows that the system is unstable for certain values of the SV
phase parameter.
