Chiral Majorana Fermion Modes on the Surface of Superconducting Topological Insulators
Ching-Kai Chiu, Guang Bian, Hao Zheng +4
The surface of superconducting topological insulators (STIs) has been recognized as an effective superconductivity platform for realizing elusive Majorana fermions. Chira…
Type-II Dirac surface states in topological crystalline insulators
Ching-Kai Chiu, Y. -H. Chan, Xiao Li +2
We study the properties of a family of anti-pervoskite materials, which are topological crystalline insulators with an insulating bulk but a conducting surface. Using ab-initio DFT…
Engineering of many-body Majorana states in a topological insulator/s-wave superconductor heterostructure
Hsiang-Hsuan Hung, Jiansheng Wu, Kuei Sun +1
We study a vortex chain in a thin film of a topological insulator with proximity-induced superconductivity---a promising platform to realize Majorana zero modes (MZMs)---by modelin…
Induced spectral gap and pairing correlations from superconducting proximity effect
Ching-Kai Chiu, William S. Cole, S. Das Sarma
We theoretically consider superconducting proximity effect, using the Bogoliubov-de Gennes theory, in heterostructure sandwich-type geometries involving a normal s-wave superconduc…
