Abstract
We show that electron transport through a long multichannel wire, connected to leads by tunnel junctions, at low temperatures and voltages is dominated by inelastic cotunnelling. This mechanism results in experimentally observed power-law dependence of conductance on temperature and voltage, in the diffusive regime where usual Coulomb anomaly theory leads to exponentially low conductance. The power-law exponent is proportional to the distance between contacts.

Comments
Calculational mistake is corrected: the power-law exponent in Eq.(6) is found to be independent on the position of contacts with respect to the ends of the wire
