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 i…
Robust Majorana Platform Driven by a Meissner-Induced Anisotropic Doppler Shift
Xiao-Hong Pan, Si-Qi Yu, Li Chen +2
The realization of robust Majorana zero modes (MZMs), a cornerstone for fault-tolerant quantum computing, is hindered by the challenge of creating a platform that simultaneously of…
Spin-Polarized Josephson Supercurrent in Nodeless Altermagnets
Chuang Li, Jin-Xing Hou, Fu-Chun Zhang +2
Long-range propagation of equal-spin triplet Cooper pairs typically occurs in ferromagnet/-wave superconductor junctions, where net magnetization plays a crucial role. Here, we…
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…
Anisotropic and tunable vortex topology in multiband iron-based superconductors
Si-Qi Yu, Wei Cheng, Chuang Li +4
Building on the multiband nature of iron-based superconductors (FeSCs), we have uncovered pronounced anisotropy in Majorana vortex topology arising from the interaction between vor…
