General theory of Josephson Diodes
Yi Zhang, Yuhao Gu, Pengfei Li +2
Motivated by recent progress in the superconductivity nonreciprocal phenomena, we study the general theory of Josephson diodes. The central ingredient for Josephson diodes is the a…
Gapless excitations inside the fully gapped kagome superconductors AVSb
Yuhao Gu, Yi Zhang, Xilin Feng +2
The superconducting gap structures in the transition-metal-based kagome metal AVSb (A=K,Rb,Cs), the first family of quasi-two-dimensional kagome superconductors, remain elu…
Low-energy effective theory and symmetry classification of flux phases on Kagome lattice
Xilin Feng, Yi Zhang, Kun Jiang +1
Motivated by recent experiments on AVSb (A=K,Rb,Cs), the chiral flux phase has been proposed to explain time-reversal symmetry breaking. To fully understand the physics beh…
Gapless vortex bound states in superconducting topological semimetals
Yi Zhang, Shengshan Qin, Kun Jiang +1
We find that the vortex bound states in superconducting topological semimetals are gapless owing to topological massless excitations in their normal states. We demonstrate this uni…
