Supercurrent and Electromotive force generations by the Berry connection from many-body wave functions
arXiv:2301.05559 · doi:10.1088/1751-8121/acc858
Abstract
The velocity field composed of the electromagnetic field vector potential and the Berry connection from many-body wave functions explains supercurrent generation, Faraday's law for the electromotive force (EMF) generation, and other EMF generations whose origins are not electromagnetism. An example calculation for the EMF from the Berry connection is performed using a model for the cuprate superconductivity.
