Second-order Topological Superconductors with Mixed Pairing
Xiaoyu Zhu
We show that a two-dimensional semiconductor with Rashba spin-orbit coupling could be driven into the second-order topological superconducting phase when a mixed-pairing state is i…

Tunable Majorana corner states in a two-dimensional second-order topological superconductor induced by magnetic fields
Xiaoyu Zhu
A two-dimensional second-order topological superconductor exhibits a finite gap in both bulk and edges, with the nontrivial topology manifesting itself through Majorana zero modes…

Tricritical Ising phase transition in two-ladder Majorana fermion lattice
Xiaoyu Zhu, Marcel Franz
We introduce a two-ladder lattice model with interacting Majorana fermions that could be realized on the surfaces of a topological insulator film. We study this model by a combinat…
