Query: Nonthermal broadening in the conductance of double quantum dot
  structures   We study the transport properties of a double quantum dot (DQD) molecule at
zero and at finite temperature. The properties of the zero temperature
conductance depends on whether the level attraction between the symmetric and
antisymmetric states of the DQD, produced by the coupling to the leads, exceeds
or not the interdot tunneling. For finite temperature we find a remarkable
nonthermal broadening effect of the conductance resonance, when the energy
levels of the individual dots are detuned.
