Magnetic-Free Quantum Interference and Universal Josephson Diode Effect Driven by a Supercurrent Gauge Field
Haowei Ye, Wenxue He, Kaixuan Fan +8
The Josephson effect, a hallmark of superconducting phase coherence, drives modern quantum technologies. However, Josephson-based quantum interference has hitherto been tethered to…
Observation of field-odd and field-free superconducting diode effects in nanoflakes
Wei Gao, Kaixuan Fan, Menghan Li +8
The superconducting diode effect (SDE) enables nonreciprocal supercurrent flow, holding immense potential for ultra-low-power quantum electronics. Intrinsic SDE typically requires…
High-Performance KVSb/WSe van der Waals Photodetectors
Yang Yang, Shaofeng Rao, Yuxuan Hou +7
Kagome metals AVSb (A = K, Rb, Cs) have recently emerged as a promising platform for exploring correlated and topological quantum states, yet their potential for optoelectr…
Asymmetric quantum Hall effect and diminished longitudinal resistance in graphene/InSe heterostructures
Wenxue He, Shijin Li, Jinhao Cheng +9
We investigate quantum transport in graphene/InSe heterostructures and find major asymmetries in the longitudinal resistance () and vanishing peaks at high magneti…
Superconductivity at Pd/BiSe Interfaces Due to Self-Formed PdBiSe Interlayers
Kaixuan Fan, Ze Hua, Siyao Gu +7
Understanding the physical and chemical processes at the interface of metals and topological insulators is crucial for developing the next generation of topological quantum devices…
