The Quadrupole Moment of Higher-Order Topological Insulator at Finite temperature
Yiting Deng, Yan He
We study the higher-order topological insulators at finite temperature based on a generalized real-space quadrupole moment, which extends the ground state expectations to ensemble…

Disorder effects on the Topological Superconductor with Hubbard Interactions
Yiting Deng, Yan He
We study the two-dimensional disordered topological superconductor with Hubbard interactions. When the magnitude of the pairing potential is tuned to special values, this interacti…

Exact Solutions of Topological Superconductor Model with Hubbard Interactions
Yiting Deng, Yan He
We study a two-dimensional model of topological superconductor with equal spin pairing and repulsive Hubbard interaction. When the pairing gap equals to the hopping constant, half…
