Quantized Berry Phase and Surface States under Reflection Symmetry or Space-Time Inversion Symmetry
C. -K. Chiu, Y. -H. Chan, A. P. Schnyder
As reflection symmetry or space-time inversion symmetry is preserved, with a non-contractible integral loop respecting the symmetry in the Brilliouin zone, Berry phase is quantized…

Fractional Josephson Effect with and without Majorana Zero Modes
Ching-Kai Chiu, S. Das Sarma
It is known that the low-energy physics of the Josephson effect in the presence of Majorana zero modes exhibits a periodicity as the Aharonov-Bohm flux varies in contrast to t…

Topological band crossings in hexagonal materials
Jonathan Zhang, Y. -H. Chan, Ching-Kai Chiu +3
Topological semimetals exhibit band crossings near the Fermi energy, which are protected by the nontrivial topological character of the wave functions. In many cases, these topolog…
