A correlated Anderson insulator on the honeycomb lattice
Tianxing Ma, Lufeng Zhang, Chia-Chen Chang +2
We study the effect of disorder on the semimetal -- Mott insulator transition in the half-filled repulsive Hubbard model on a honeycomb lattice, a system that features vanishing de…
Disorder effects in correlated topological insulators
Hsiang-Hsuan Hung, Aaron Barr, Emil Prodan +1
Using exact diagonalization and quantum Monte Carlo calculations we investigate the effects of disorder on the phase diagram of both non-interacting and interacting models of two-d…
Engineering of many-body Majorana states in a topological insulator/s-wave superconductor heterostructure
Hsiang-Hsuan Hung, Jiansheng Wu, Kuei Sun +1
We study a vortex chain in a thin film of a topological insulator with proximity-induced superconductivity---a promising platform to realize Majorana zero modes (MZMs)---by modelin…
Phase diagram of a frustrated asymmetric ferromagnetic spin ladder
Lihua Pan, Depeng Zhang, Hsiang-Hsuan Hung +1
We perform a systematic investigation on the ground state of an asymmetric two-leg spin ladder (where exchange couplings of the legs are unequal) with ferromagnetic (FM) nearest-ne…
Correlation effects in pyrochlore iridate thin films grown along the direction
Qi Chen, Hsiang-Hsuan Hung, Xiang Hu +1
Over the past few years bulk pyrochlore iridates of the form IrO (where is a rare earth element, Ir is iridium, and O is oxygen) have been studied as model systems…
Short-ranged interaction effects on topological phase transitions: The perturbative mean-field method
Hsin-Hua Lai, Hsiang-Hsuan Hung
Time-reversal symmetric topological insulator is a novel state of matter that a bulk-insulating state carries dissipationless spin transport along the surfaces, embedded by the $Z_…
