Nonlocal thermoelectricity in quantum wires as a signature of Bogoliubov-Fermi points
Abstract
We study nonlocal thermoelectricity in a superconducting wire subject to spin-orbit coupling and a magnetic field with a relative orientation θ between them. We calculate the current flowing in a normal probe attached to the bulk of a superconducting wire, as a result of a temperature difference applied at the ends of the wire. We focus on the linear response regime, corresponding to a small temperature bias. We find that the nonlocal thermoelectric response is strongly dependent on the angle θ and occurs in ranges which correspond to the emergence of Bogoliubov-Fermi points in the energy spectrum of the superconducting wire.
