Direct visualization of sign reversal s^+- superconducting gaps in FeTe0.55Se0.45
Mingyang Chen, Qingkun Tang, Xiaoyu Chen +7
In many unconventional superconductors, the pairing of electrons is driven by the repulsive interaction, which leads to the sign reversal of superconducting gaps along the Fermi su…
Spin-triplet -wave pairing in twisted bilayer graphene near 1/4 filling
Q. K. Tang, L. Yang, D. Wang +2
We investigate the twisted bilayer graphene by a two-orbital Hubbard model on the honeycomb lattice. The model is studied near 1/4 band filling by using the singular-mode functiona…
Directly visualizing the sign change of d-wave superconducting gap in Bi2Sr2CaCu2O8+δ by phase-referenced quasiparticle interference
Qiangqiang Gu, Siyuan Wan, Qingkun Tang +7
The superconducting state is achieved by the condensation of Cooper pairs and is protected by the superconducting gap. The pairing interaction between the two electrons of a Cooper…
Visualizing the -vector in a nematic triplet superconductor
Wei-Cheng Bao, Qing-Kun Tang, Da-Chuan Lu +1
Recent experiments show strong evidences of nematic triplet superconductivity in doped BiSe and in BiTe thin film on a superconducting substrate, but with varying i…
