Magnetic field effects on $T_{c}$ and the pseudogap onset temperature in cuprate superconductors

Qijin Chen, Ying-Jer Kao, Andrew P. Iyengar +1

We study the sensitivity of $T_{c}$ and the pseudogap onset temperature, $T^{*}$ , to low fields, $H$ , for cuprate superconductors, using a BCS-based approach extended to arbitrary coup…

Pairing fluctuation theory of high $T_{c}$ superconductivity in the presence of nonmagnetic impurities

Qijin Chen, J. R. Schrieffer

The pseudogap phenomena in the cuprate superconductors requires a theory beyond the mean field BCS level. A natural candidate is to include strong pairing fluctuations, and treat t…
