Query: Reaction rates in squeezed polaron bands controlled by quantum
  statistics   Reaction rates are often defined using classical statistics for introducing
the thermal occupation probabilities. Its predictions for the temperature
dependence of a rate are found in reasonable agreement with experiments. In
view of the applications to polaronic systems at lower temperatures under
strongly quantized conditions, we now extend the definition so as to
incorporate quantum statistics as well, Fermi-Dirac for polarons and
Bose-Einstein for bipolarons. We find both extensions feasible.
