Boundary criticality in two-dimensional correlated topological superconductors
Yang Ge, Huan Jiang, Hong Yao +1
The presence of a boundary enriches the nature of quantum phase transitions. However, the boundary critical phenomena in topological superconductors remain underexplored so far. He…

Boundary criticality in two-dimensional interacting topological insulators
Yang Ge, Hong Yao, Shao-Kai Jian
We study the boundary criticality in 2D interacting topological insulators. Using the determinant quantum Monte Carlo method, we present a nonperturbative study of the boundary qua…

Boundary criticality for the Gross-Neveu-Yukawa models
Huan Jiang, Yang Ge, Shao-Kai Jian
We study the boundary criticality for the Gross-Neveu-Yukawa (GNY) models. Employing interacting Dirac fermions on a honeycomb lattice with armchair boundaries, we use determinant…
