Microscopic study of supercurrent diode effect in chiral nanotubes
Chuang Li, James Jun He
Nonreciprocity of supercurrents may exist when both spatial inversion and time-reversal symmetries are broken, leading to the supercurrent diode effect (SDE). The spatial inversion…

Optical response of edge modes in time-reversal symmetric topological superconductors
Hirokazu Kobayashi, Han Bi, James Jun He +1
Topological superconductors and Majorana edge modes at their boundaries have been theoretically predicted. However, their experimental observation remains controversial. Recent the…

Inter-band optical transitions of helical Majorana edge modes in topological superconductors
Han Bi, James Jun He
The search for evidence of Majorana states on the edges of topological superconductors (TSCs) is challenging due to the difficulty of detecting such charge-neutral electronic quasi…
