Nonreciprocal Superconducting Transport from Chiral Edge States
Jin-Xing Hou, Yan-Song Song, James Jun He +1
Nonreciprocal superconducting transport enables dissipationless rectification and has attracted considerable interest, yet its microscopic origin is typically sought in bulk electr…
Strong Correlation Drives Zero-Field Josephson Diode Effect
Yiheng Sun, Zhenyu Zhang, James Jun He
The supercurrent diode effect (SDE), characterized by unequal critical currents in opposite directions, has been observed with or without magnetic fields, yet mechanisms enabling z…
Directional-dependent Berezinskii-Kosterlitz-Thouless transition at EuO/KTaO(111) interfaces
Zongyao Huang, Zhengjie Wang, Xiangyu Hua +10
In two dimensions, a phase-coherent superconducting state is established via a Berezinskii-Kosterlitz-Thouless (BKT) transition, whose critical temperature is determi…
Dual-mode superconducting diode effect enabled by in-plane and out-of-plane magnetic field
Chengyu Yan, Huai Guan, Zhenyu Zhang +6
The discovery of the superconducting diode effect (SDE) has been cherished as a milestone in developing superconducting electronics. Tremendous efforts are being dedicated to reali…
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…
