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…
Constraints on the orbital flux phase in VSb from polar Kerr effect
Hao-Tian Liu, Junkang Huang, Tao Zhou +1
The VSb ( K, Rb, Cs) family of Kagome metals hosts unconventional charge density wave order whose nature is still an open puzzle. Accumulated evidences point to a ti…
