Driving the field-free Josephson diode effect using Kagome Mott insulator barriers
Michiel P. Dubbelman, Heng Wu, Joost Aretz +9
Josephson junctions (JJs), devices consisting of two superconductors separated by a barrier, are of great technological importance, being a cornerstone of quantum information proce…
Polarization Controlled Supercurrent in Ferroelectric Josephson Junction
Yaozu Tang, Mazhar N. Ali, Gerrit E. W. Bauer +1
Josephson junctions are essential devices in superconducting electronics and quantum computing hardware. Here we predict electrical control of the supercurrent in composite superco…
Supercurrent interference and its transfer in a kagome superconductor
Heng Wu, Houssam el Mrabet Haje, Michiel Dubbelman +4
Superconductivity represents a macroscopic quantum state notable for its rich manifestations of electronic coherence and collective behavior. Kagome materials AV3Sb5 (A= K, Cs, Rb)…
Unveiling Topological Hinge States in the Higher-Order Topological Insulator WTe Based on the Fractional Josephson Effect
Yong-Bin Choi, Jinho Park, Woochan Jung +3
Higher-order topological insulators (HOTIs) represent a novel class of topological materials, characterised by the emergence of topological boundary modes at dimensions two or more…
The global critical current effect of superconductivity
Heng Wu, Yaojia Wang, Mazhar N. Ali
Superconductivity has been investigated for over a century, but there are still open questions about what determines the critical current; the maximum current a superconductor can…
Pressure-dependent magnetotransport measurement in Kagome metal YbCo_3Ge
Zhiyuan Cheng, Yaojia Wang, Heng Wu +3
Kagome materials are known to be an ideal platform that hosts a plethora of interesting phases such as topological states, electronic correlation, and magnetism, owing to their uni…
