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…

Electromagnetic responses of bilayer excitonic insulators: from exciton London equations to dipole and inverse dipole Hall effects

Yuelin Shao, Hao Shi, Xi Dai

We develop a microscopic theory of the linear electromagnetic response of bilayer excitonic insulators relevant to electron-hole double-layer systems. Using a self-consistent Hartr…

Two-dimensional moiré phonon polaritons

Hao Shi, Chu Li, Ding Pan +1

Phonon polaritons (PhPs) are hybrid light-matter modes. We investigate them in two-dimensional (2D) materials with twisted moiré structures, revealing that the moiré potential crea…

Link between cascade transitions and correlated Chern insulators in magic-angle twisted bilayer graphene

Qianying Hu, Shu Liang, Xinheng Li +3

Chern insulators are topologically non-trivial states of matter characterized by incompressible bulk and chiral edge states. Incorporating topological Chern bands with strong elect…

Moiré optical phonons dancing with heavy electrons in magic-angle twisted bilayer graphene

Hao Shi, Wangqian Miao, Xi Dai

Electron-phonon coupling in magic-angle twisted bilayer graphene is an important but difficult topic. We propose a scheme to simplify and understand this problem. Weighted by the c…
