Electronically Inactive Intercalated LaNiO Layer in Superconducting LaNiO
Tianyang Xie, Yuxin Wang, Zhan Wang +2
The authors use density functional theory, Wannier tight‑binding, and slave‑boson calculations to show that the intercalated La₂NiO₄ layer in superconducting La₅Ni₃O₁₁ is insulatin…
Anisotropic vortex motion and two-dimensional superconducting transition
Zhipeng Xu, Kun Jiang, Jiangping Hu
Vortex motion plays a central role in determining the resistance of two-dimensional superconductors, both in the context of the Berezinskii-Kosterlitz-Thouless (BKT) transition and…
Spin Dynamics from Niu-Kleinman Adiabatic Approach and Slave Boson Mean Field Theory
Xuan Yang, Tianyang Xie, Shaohang Shi +2
Spin-wave excitations provide a central probe of magnetic order and electronic correlations in strongly correlated materials. In this work, we develop an adiabatic theory of spin d…
Interband pairing as the origin of the sublattice dichotomy in monolayer FeSe/SrTiO_3
Zhipeng Xu, Shengshan Qin, Kun Jiang +1
Sublattice dichotomy in monolayer FeSe/SrTiO, signaling the breaking of symmetries exchanging the two Fe sublattices, has recently been reported. We propose that interband pair…
Sublattice Dichotomy in Monolayer FeSe Superconductor
Cui Ding, Zhipeng Xu, Xiaotong Jiao +8
The pairing mechanism behind the monolayer FeSe is one essential question for iron-based superconductors. In this work, we show the sublattice degree of freedoms of monolayer FeSe…
Evidence of P-wave Pairing in KCrAs Superconductors from Phase-sensitive Measurement
Zhiyuan Zhang, Ziwei Dou, Anqi Wang +21
P-wave superconductors hold immense promise for both fundamental physics and practical applications due to their unusual pairing symmetry and potential topological superconductivit…
