Topological properties and phase diagram of the triangular Hofstadter model with staggered flux
Qi Gao, Wei Chen
We study the topological properties and phase diagram of the triangular Hofstadter model with staggered flux in adjacent triangles in this work. This lattice can be used to describ…

Localization phase diagram of the Hexagonal Lattice with irrational magnetic flux
Qi Gao, Shuo Zhang, Wei Chen
We study the Hofstadter model on a hexagonal lattice with irrational magnetic flux in this work. The Hofstadter model of the square lattice with irrational flux has been solved mat…

Dielectric and optical markers originating from quantum geometry
Wei Chen
We elaborate that many non-excitonic dielectric and optical properties of semiconductors and insulators caused by interband absorption are originated from quantum geometry, includi…
