Self-consistent theory of pair density waves in kagome superconductors
Meng Yao, Yan Wang, Da Wang +2
Pair density wave (PDW) is an intriguing quantum matter proposed in the frontier of condensed matter physics. However, the existence of PDW in microscopic models has been rare. In…
Necklace-like pattern of vortex bound states
Zhiyong Hou, Kailun Chen, Wenshan Hong +8
Vortex is a topological defect in the superconducting condensate when a magnetic field is applied to a type-II superconductor, as elucidated by the Ginzburg-Landau theory. Due to t…
Anomalous isotope Effect in d-wave superconductors on the square lattice
Gan Sun, Qing-Geng Yang, Da Wang +1
Isotope effect with a large coefficient is usually taken as an evidence of phonon mediated superconductors in the Bardeen-Cooper-Schrieffer (BC…
Quantized bound states around a vortex in anisotropic superconductors
Ke Xiang, Da Wang, Qiang-Hua Wang
The bound states around a vortex in anisotropic superconductors is a longstanding yet important issue. In this work, we develop a variational theory on the basis of the Andreev app…
Charge bond order and s-wave superconductivity in the kagome lattice with electron-phonon coupling and electron-electron interaction
Qing-Geng Yang, Meng Yao, Da Wang +1
The effects of optical bond phonons coupled to electrons in two-dimensional lattices have attracted much interest recently, with the hope to explore unconventional superconducting…
Electronic orders on the kagome lattice at the lower Van Hove filling
Yi-Qun Liu, Yan-Bin Liu, Wan-Sheng Wang +2
We study the electronic orders at the lower van Hove filling in the kagome lattice. In the weak limit of the Hubbard interaction versus the hopping parameter , we find that…
Effective model and -wave superconductivity in trilayer nickelate LaNiO
Qing-Geng Yang, Kai-Yue Jiang, Da Wang +2
The recent discovery of bulk superconductivity in trilayer nickelate LaNiO with the critical temperature near K under high pressure is attracting a new wav…
