Higher-Order Topological States with Cleavage-Dependent Dirac Mass
Hongyu Chen, Min Long, Chuang Chen +1
Topological quantum chemistry based on local charge profiles lacks predictive power for the crystalline cleavage of higher-order topological insulators (HOTIs). By cleaving an obst…
Many-Anyon Braiding in Non-Abelian Fractional Quantum Hall Effect with Hybrid Monte Carlo Simulation
Ting-Tung Wang, Ha Quang Trung, Qianhui Xu +3
We employ the hybrid Monte Carlo method to efficiently compute the many-anyon non-Abelian braiding matrices associated with different braiding schemes of the Moore-Read quasiholes.…
Chiral Graviton Modes in Non-Abelian lattice Fractional Quantum Hall states
Zeno Bacciconi, Min Long, Hernan Xavier +3
Synthetic quantum matter provides a highly tunable route to fractional quantum Hall physics beyond the constraints of conventional electronic materials. However, previous theoretic…
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…
Spin excitations arising from anisotropic Dirac spinons in YCu(OD)Br[Br(OD)]
Lankun Han, Zhenyuan Zeng, Min Long +10
A Dirac quantum spin liquid hosts Dirac spinons, which are low-energy fractionalized neutral quasiparticles with spin 1/2 that obey the Dirac equation. Recent inelastic neutron sca…
