Query: Influence of superconducting leads energy gap on electron transport
  through double quantum dot by Markovian quantum master equation approach   The superconducting reservoir effect on the current carrying transport of a
double quantum dot in Markovian regime is investigated. For this purpose, a
quantum master equation (QME) at finite temperature is derived for the
many-body density matrix of an open quantum system. The dynamics and the
steady-state properties of the double quantum dot system for arbitrary bias are
studied. We will show that how the populations and coherencies of the system
states are affected by superconducting leads. The energy parameter of system
contains essentially four contributions due to dots system-electrodes coupling,
intra dot coupling, two quantum dots inter coupling and superconducting gap.
The coupling effect of each energy contribution is applied to currents and
coherencies results. In addition, the effect of energy gap is studied by
considering the amplitude and lifetime of coherencies to get more current
through the system.
