Gauge-covariant magnetic Bloch sums for general multiorbital Hofstadter models
Hao Shi, Tianyu Qiao, Wangqian Miao +3
We formulate a unified treatment of the Hofstadter problem for general two-dimensional multiorbital Peierls tight-binding Hamiltonians using a gauge-covariant magnetic Bloch-sum ba…

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…

Emergence of Topological Electron Crystals in Bilayer Graphene--Mott Insulator Heterostructures
Wangqian Miao, Tianyu Qiao, Xue-Yang Song +4
The interplay between strong electron correlation and band topology offers a playground for discovering exotic quantum phases. Here, we predict the emergence of topological electro…
