Webb摘要： In this work we numerically investigate the fate of the Bardeen-Cooper-Schrieffer (BCS) pairing in the presence of quenched phase under Peierls substitution using time-dependent real space and momentum space Bogoliubov-de Gennes equation methods and Anderson pseudospin representation method. WebbWhile this expression is derived for zero magnetic field, by choosing the integration path to be the shortest distance over nearest neighbor bond, this expression is used to include …
