Ising Dirac fermions across a topological phase transition
Aoqian Zhang, Yaqi Ma, Yifei Jin +14
Dirac fermions have attracted significant interest due to their relativistic dispersions and close connections to topological physics, yet they are generally expected to be gapped…

Observation of a Mott quantum spin Hall insulator in twisted WSe2
Yifei Jin, Yaqi Ma, Aoqian Zhang +9
Quantum spin Hall (QSH) insulators and Mott insulators are conventionally regarded as distinct insulating phases, arising from band topology and strong Coulomb interactions, respec…
