Impurity-Scattering Assisted Umklapp Scattering as the Origin of Low-Temperature Resistivity in the Normal-State of Cuprate Superconductors

Xingyu Ma, Minghuan Zeng, Huaiming Guo +1

The transport experiments reveal that the low-temperature resistivity in the normal-state of cuprate superconductors is quadratic in temperature (T-quadratic) in the underdoped pse…

Bogoliubov sum rule and the Knight-shift ellipsoid in spin-locked superconductors

Yi Zhou

We establish an exact Bogoliubov sum rule for any Hermitian single-particle operator $O$ : at each momentum, its particle-hole and particle-particle matrix-element weights sum to th…

Persistent Fermi Pockets and Robust Electron Pairing in Lightly Doped CuO $_{2}$ Planes of Cuprate Superconductors

Hao Chen, Jumin Shi, Yinghao Li +23

High temperature superconductivity in cuprate superconductors is generally considered to be generated from doping the Mott insulators. The fundamental nature of the doped parent co…
