Tunable superconductivity and spin density wave in La3Ni2O7/LaAlO3 thin films
Yu-Han Cao, Kai-Yue Jiang, Hong-Yan Lu +2
Recently, La3Ni2O7 thin film on the LaAlO3 substrate is shown to be superconducting, while the bulk La3Ni2O7 with the same in-plane lattice constant under pressure does not superco…
Genuine pair density wave order on the kagome lattice
Han-Yang Liu, Da Wang, Ziqiang Wang +1
The pair density wave (PDW) is a novel superconducting state with non-zero center-of-mass momentum Cooper pairing in the absence of external magnetic fields. Its realization in mic…
Phase-sensitive evidence for pair density waves in a kagome superconductor
Xiao-Yu Yan, Guowei Liu, Hanbin Deng +22
Pair density wave (PDW) exhibits periodic amplitude and sign modulations of the superconducting order parameter. Such a pairing state has long been proposed to be highly sensitive…
Strain-Engineered Electronic Structure and Superconductivity in LaNiO Thin Films
Yu-Han Cao, Kai-Yue Jiang, Hong-Yan Lu +2
Recently, the films of the Ruddlesden-Popper (RP) nickelate superconductors, in which the (La,Pr)NiO system exhibits a remarkable transition temperature exceeding…
Quantum interference among vortex bound states in superconductors
Yi-Ming Fu, Da Wang, Qiang-Hua Wang
In a recent experiment (Hou et al Phys. Rev. X 15, 011027), a new type of necklace-like vortex bound state (VBS) was observed and attributed to disorder induced interference among…
Variational Quantum Monte Carlo investigations of the superconducting pairing in LaNiO
Yi-Qun Liu, Da Wang, Qiang-Hua Wang
We investigate the pairing symmetry in the novel superconductor LaNiO under pressure by the non-perturbative variational quantum Monte Carlo. Within the bilayer Hubbard…
Yin-Yang vortex on UTe2 (011) surface
Ruotong Yin, Yuanji Li, Zengyi Du +14
UTe2 is a promising candidate for spin-triplet superconductor, yet its exact superconducting order parameter remains highly debated. Here, via scanning tunneling microscopy/spectro…
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…
