On local temperatures near absolute zero in nonequilibrium quantum systems
Abstract
The local temperature of a quantum conductor with source at finite temperature and drain at or near absolute zero is investigated, a problem outside the scope of linear response theory. The local temperature is defined by the measurement of a floating thermoelectric probe. It is shown that cold spots with local temperatures near absolute zero exist within the system, and the applicability of the third law of thermodynamics is investigated.
