The thermoelectric effect in superconductors
Abstract
Macroscopic Ginzburg-Landau theory is used to investigate the thermoelectric effect in a superconducting ring. An exact solution is obtained for the model case of a homogeneous superconducting cylinder in which a normal excitation current is prescribed. The total ambient current and magnetic field in the cylinder cavity are found to arise as a response to this normal excitation current. The main conclusion of the present study is that a profound analogy exists between the behavior of a thermoelectric system and the behavior of a hollow superconducting cylinder in an external field. Both systems are characterized by the presence of quantum levels which characterize the possible number of flux quanta frozen in the cavity.
