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…
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…
Josephson diode effect: a phenomenological perspective
Da Wang, Qiang-Hua Wang, Congjun Wu
As a novel quantum phenomenon with nonreciprocal supercurrent, the Josephson diode effect was intensively studied in recent years. Here, we construct a generalized resistively capa…
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…
