Chiral Majorana Hinge Modes in Superconducting Dirac Materials
Bo Fu, Zi-Ang Hu, Chang-An Li +2
Chiral Majorana hinge modes are characteristic of a second-order topological superconductor in three dimensions. Here we systematically study pairing symmetry in the point group D_…

Quantum Monte Carlo study of topological phases on a spin analogue of Benalcazar-Bernevig-Hughes model
Jiaojiao Guo, Junsong Sun, Xingchuan Zhu +3
We study the higher-order topological spin phases based on a spin analogue of Benalcazar-Bernevig-Hughes model in two dimensions using large-scale quantum Monte Carlo simulations.…

Topological Phase Transitions in Disordered Electric Quadrupole Insulators
Chang-An Li, Bo Fu, Zi-Ang Hu +2
We investigate disorder-driven topological phase transitions in quantized electric quadrupole insulators. We show that chiral symmetry can protect the quantization of the quadrupol…
