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…

Inverse-current quantum electro-oscillations in a charge-density wave insulator
Tian Le, Ruiyang Jiang, Linfeng Tu +14
Quantum magneto-oscillations have long been a vital subject in condensed matter physics, with ubiquitous quantum phenomena and diverse underlying physical mechanisms. Here, we demo…
