Therefore, we focus on the question of whether the combination of the local, nonlocal electrical and the thermal conductance can separate the good, bad, and ugly zero-bias conductance peaks in finite-length wires.

When a system is thermally coupled to only a small part of a larger bath, statistical fluctuations of the temperature (more precisely, the internal energy) of this "sub-bath" around the mean temperature defined by the larger bath can become significant.
