Helical Rashba-exchange gauge field drives a uniaxial pair density wave in EuRbFeAs
Pengfei Li, Yi Zhou
The recent discovery of an intrinsic, zero-field pair density wave (PDW) in the iron-pnictide superconductor EuRbFeAs poses a fundamental puzzle: how does a unidirectional,…

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 : at each momentum, its particle-hole and particle-particle matrix-element weights sum to th…

Pressure induced superconductivity bordering a charge-density-wave state in NbTe4 with strong spinorbit coupling
Xiaojun Yang, Yonghui Zhou, Mengmeng Wang +13
Transition-metal chalcogenides host various phases of matter, such as charge-density wave (CDW), superconductors, and topological insulators or semimetals. Superconductivity and it…
