Query: Novel Transport Mechanism for Interacting Electrons in Disordered
  Systems: Variable-Range Resonant Tunneling   To interpret recent experimental observations of the phononless hopping
conduction, we suggest a novel transport mechanism according to which the
current-carrying single electrons move via quantum resonant tunneling between
localized states brought into resonance by fast electron hops in their
environment.
