Collective phase modes in twisted -wave superconducting bilayers
Yin Shi, Mengxian Zhao, Fei Yang +2
Twisted cuprate bilayers have been predicted to host high-temperature chiral superconductivity, originating from higher-order Josephson coupling processes. In such two-dime…
Quench of chiral superconductivity by quantum phase fluctuations in twisted cuprate bilayers
Yin Shi, Mengxian Zhao, Fei Yang +2
Following theoretical proposals of chiral superconductivity in twisted cuprate bilayers, experimental signatures of time-reversal symmetry breaking (TRSB) remain highly con…
Excitonic-Superconducting Coexistence and Emergent Nematic Superconductivity Driven by Spontaneous Symmetry Breaking
Fei Yang, Ruigang Li, Junwei Liu +1
Excitonic insulating (EI) and superconducting (SC) orders are generally regarded as mutually exclusive electronic instabilities. Within a self-consistent microscopic theory, we stu…
Exact theory of superconductivity in a strongly correlated Fermi-arc model
Xianliang Zhou, Fei Yang, Miao Liu +2
Because the normal state of underdoped cuprate superconductors is an enigmatic Fermi-arc metal, it is valuable to analyze an exactly solvable model that exhibits both Fermi arcs an…
Dephasing-induced Quantum Hall Criticality in the Quantum Anomalous Hall system
Fei Yang, Dong E. Liu
Conventional wisdom holds that static disorder is indispensable to the integer quantum Hall effect, underpinning both quantized plateaus and the plateau-plateau transition. We show…
Dissecting coupled orders in a terahertz-driven electron-doped cuprate
Liwen Feng, Haotian Zhang, Tim Priessnitz +16
The interplay between superconductivity and charge density wave has often been studied from an equilibrium point of view. For example, using static tuning knobs such as doping, mag…
