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…

Vortices in Two-Dimensional Chiral Superfluids
Yan He, Wenxing Nie
We study the orbital angular momentum (OAM) of two-dimensional chiral -wave superfluids (SFs) in the presence of an axisymmetric multiply quantized vortex (MQV)…

Two-component repulsive atomic Fermi gases in a thin spherical shell
Yan He, Chih-Chun Chien
We present possible ground-state structures of two-component atomic Fermi gases with repulsive interactions in a thin spherical shell geometry by implementing a self-consistent Har…
