Sequential Topological Superconductivity in a Square Lattice with Chiral Charge Density Waves
Zhong-Xian Jin, Junkang Huang, Yu-Xuan Li +1
The interplay between charge order and superconductivity offers a fertile ground for emergent quantum phases. Here we theoretically investigate a square-lattice superconductor coex…
Direction-selective triplet pairing and spin-edge locking in altermagnetic metals
Lie Yuan, Junkang Huang, Yu-Xuan Li +1
We investigate self-consistent unconventional superconductivity in a two-dimensional -wave altermagnetic metal. We find that momentum-dependent altermagnetic spin splitting supp…
Higher-order topological superconductivity in type-II time-reversal-symmetric Weyl semimetals with a hybrid pairing
Junkang Huang, Z. D. Wang, Tao Zhou
We employed the self-consistent method on a two-orbital type-II time-reversal-symmetric Weyl semimetal, revealing a hybrid pairing of singlet -wave and triplet -wave. We pres…
Effective perpendicular electric field as a probe for interlayer pairing in ambient-pressure superconducting LaPrNiO thin films
Junkang Huang, Tao Zhou
Recent angle-resolved photoemission spectroscopy (ARPES) experiments on LaPrNiO thin films have revealed a superconducting gap near the diagonal direction…
Probing Sign-Changing Order Parameters via Impurity States in unconventional superconductors: Implications for LaNiO Superconductors with interlayer pairing
Junkang Huang, Z. D. Wang, Tao Zhou
Motivated by the desire to investigate the fundamental relationship between impurity-induced states and the sign change of the superconducting order parameter, as well as to explor…
Spin excitations in bilayer LaNiO superconductors with the interlayer pairing
Meiyu Lu, Tao Zhou
Prompted by the recent discovery of high-temperature superconductivity in LaNiO under pressure, this study delves into a theoretical investigation of spin excitations w…
