Discrete Shift and Polarization from Response to Symmetry Defects in Interacting Topological Phases
Lu Zhang, Min Long, Yuxuan Zhang +2
We extend the previous study of extracting crystalline symmetry-protected topological invariants to the correlated regime. We construct the interacting Hofstadter model defined on…

Spectra of Magnetoroton and Chiral Graviton Modes of Fractional Chern Insulator
Min Long, Hongyu Lu, Han-Qing Wu +1
Employing the state-of-the-art time-dependent variational principle (TDVP) algorithm, we compute the spectra of charge-neutral excitations in the (bosonic) \updated{ and $1…
