Query: Quantization of the Smoluchowski equation and the problem of quantum
  tunneling at zero temperature   In this article we address the problem of quantum tunneling of a
non-Markovian Brownian particle away from thermal equilibrium. We calculate the
Kramers escape rate at low temperature (including the zero temperature case) in
the Smoluchowski limit (strong friction regime). Our main findings are: (i) our
quantum escape rate is valid far from the thermal equilibrium and is
non-Markovian, but it becomes Markovian as the correlation time vanishes; (ii)
at thermodynamic equilibrium we obtain a non-Markovian quantum rate that
predicts a superfluidity phenomenon in the Markovian limit at low and zero
temperatures.
