Josephson diode effect in a line-centered honeycomb lattice based superconductor junction

YJ Wei, JJ Wang, J Wang - Physical Review B, 2023 - APS
The Josephson diode effect (JDE) is the asymmetry of the critical supercurrent flowing along
opposite current directions. We study a mechanism in this work to generate a possible JDE …
