Manipulating fractional Shapiro steps in twisted cuprate Josephson junctions
Yuying Zhu, Heng Wang, Ding Zhang +1
Highquality Josephson junctions made of twisted cuprate superconductors offer unprecedented opportunities in addressing fundamental problems and realizing nextgeneration supe…
Re-entrant superconductivity at an oxide heterointerface
D. Maryenko, M. Kawamura, I. V. Maznichenko +7
A magnetic field typically suppresses superconductivity by either breaking Cooper pairs via the Zeeman effect or inducing vortex formation. However, under certain circumstances, a…
Quantum superconducting diode effect with perfect efficiency above liquid-nitrogen temperature
Heng Wang, Yuying Zhu, Zhonghua Bai +7
The superconducting diode is an emergent device that juggles between the Cooper-paired state and the resistive state with unpaired quasiparticles. Here, we report a quantum version…
Superconducting gap and its Little-Parks like oscillations with high-order harmonics in lithium intercalated 1T-TiSe
Jia-Yi Ji, Zongzheng Cao, Yi Hu +7
The superconducting phase of doped 1T-TiSe is a fruitful playground for exploring exotic quantum phenomena such as the anomalous metal state and spontaneously formed supercondu…
