Field-free Josephson diode and tunable -junction in chiral kagome antiferromagnets
Jin-Xing Hou, Chuang Li, Lun-Hui Hu +1
The recent realization of superconducting proximity effect in chiral antiferromagnets (cAFMs) opens a new route to nonreciprocal superconducting transport of fundamental interest a…

Inter-orbital spin-triplet superconductivity from altermagnetic fluctuations
Chen Lu, Chuang Li, Chao Cao +3
Altermagnetic (AM) fluctuations are a new class of collinear spin fluctuations whose role in mediating superconductivity faces a fundamental tension: their -point peak favors in…

Vortex States and Coherence Lengths in Flat-Band Superconductors
Chuang Li, Fu-Chun Zhang, Lun-Hui Hu
Superconductivity in flat-band systems, governed by quantum metric of Bloch states rather than the BCS framework, exhibits unique phenomena due to the vanishing electron group velo…
