Exactly solvable pair-density wave in topological flat bands from magnetic translation symmetries
Zhengzhi Wu, Zhou-Quan Wan, Steven H. Simon
Pair-density wave (PDW) superconductors are exotic phases in which Cooper pairs carry finite center-of-mass momentum. Despite a variety of theoretical and experimental reports on P…
High-temperature charge-4e superconductivity in SU(4) interacting fermions
Shao-Hang Shi, Zhengzhi Wu, Jiangping Hu +1
The condensation of electron quartets, known as charge-4e superconductivity (SC), represents a novel quantum state of matter beyond the standard paradigm of Cooper pairing. However…
Emergent spacetime supersymmetry at 2D fractionalized quantum criticality
Zhengzhi Wu, Zhou-Quan Wan, Shao-Kai Jian +1
While experimental evidence for spacetime supersymmetry (SUSY) in particle physics remains elusive, condensed matter systems offer a promising arena for its emergence at quantum cr…
Boundary and defect criticality in topological insulators and superconductors
Xiaoyang Shen, Zhengzhi Wu, Shao-Kai Jian
We study the boundary criticality enriched by boundary fermions, which ubiquitously emerge in topological phases of matter, with a focus on topological insulators and topological s…
Time-Reversal Invariant Topological Moiré Flatband: A Platform for the Fractional Quantum Spin Hall Effect
Yi-Ming Wu, Daniel Shaffer, Zhengzhi Wu +1
Motivated by recent observation of the quantum spin Hall effect in monolayer germanene and twisted bilayer transition-metal-dichalcogenides (TMDs), we study the topological phases…
