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 $\nu =1/2$ (bosonic) \updated{ and $1…
