Query: The Lindblad and Redfield forms without secular approximation derived
  from Born-Markov master equation and their applications   In this paper we derive the Lindblad and Redfield forms with and without
secular approximation from the Born-Markov master equation for open quantum
systems. The spectral correlation tensor of bath (the Fourier transform of the
bath correlation function) and then the coefficients in the two forms of the
master equation are reevaluated according to the scheme in Ref.[Phys. Rev. A
99, 022118 (2019)]. They are complex numbers rather than the real numbers
getting from traditional simplified methods. The dynamics of two models [one is
an open three-level quantum system model, and the other is the model of
phycoerythrin 545 (PE545) of modeling a photosynthesis reaction center] are
studied by using the obtained equations. The non-secular Lindblad and Redfield
equations with the complex coefficients predict almost the same dynamical
results from the Born-Markov master equation. However, the results obtained
from the traditional Lindblad and Redfield equations deviate the actual
dynamics of the open quantum systems.
