Nonreciprocal superconducting critical currents with normal state field trainability in kagome superconductor CsV3Sb5
Jun Ge, Xiaoqi Liu, Pinyuan Wang +5
Determining time-reversal symmetry (TRS) and chirality in the superconducting state and its relation to normal-state symmetry and topology are important issues in condensed matter…
Demonstration of robust chiral edge transport in Chern insulator MnBi2Te4 devices with engineered geometric defects
Pinyuan Wang, Jun Ge, Jiawei Luo +4
Chiral edge states in Chern insulators are theoretically predicted to propagate unidirectionally along the sample boundary with inherent robustness against local perturbations, whi…
Time-reversal symmetry breaking superconductivity with electronic glass in nickelate (La, Pr, Sm)3Ni2O7 films
Haoran Ji, Zheyuan Xie, Yaqi Chen +11
The discovery of Ruddlesden-Popper (R-P) nickelate superconductors under high pressure heralds a new chapter of high-transition temperature (high-Tc) superconductivity. Recently, a…
Emergent quantum phenomena via phase-coherence engineering in infinite-layer nickelate superconductors
Haoran Ji, Zheyuan Xie, Xiaofang Fu +8
Dimensionality of a physical system, conventionally an invariant geometric characteristic, fundamentally governs the universality class of phase transitions and the landscape of em…
