Intrinsic and Tunable Superconducting Diode Effect in Quantum Spin Hall Systems
Samuele Fracassi, Simone Traverso, Stefan Heun +3
Nonreciprocal dissipationless transport has long been sought for applications in superconducting technologies. Recently, it has been implemented by the so called superconducting di…
Covariant field theory of 3D massive fractons
Erica Bertolini, Matteo Carrega, Nicola Maggiore +1
We construct a covariant and gauge-invariant theory describing massive fractons in three spacetime dimensions, based on a symmetric rank-2 tensor field. The model includes a Chern-…
Vortex Pinning in Niobium covered by a thin polycrystalline Gold
Wenbin Li, Ivan Villani, Ylea Vlamidis +11
Owing to its superconducting properties, Niobium (Nb) is an excellent candidate material for superconducting electronics and applications in quantum technology. Here we perform sca…
Supercurrent modulation in InSb nanoflag-based Josephson junctions by scanning gate microscopy
Antonio Lombardi, Gaurav Shukla, Giada Bucci +10
InSb nanoflags represent an interesting platform for quantum transport and have recently been exploited in the study of hybrid planar Josephson junctions. Due to the uncovered semi…
Superconducting Quantum Interference Devices based on InSb nanoflag Josephson junctions
Andrea Chieppa, Gaurav Shukla, Simone Traverso +10
Planar Josephson junctions (JJs) based on InSb nanoflags have recently emerged as an intriguing platform in superconducting electronics. This letter presents the fabrication and in…
Quasi--periodic supercurrent at quantum Hall transitions
Ivan Villani, Matteo Carrega, Alessandro Crippa +9
The combination of superconductivity and quantum Hall (QH) effect is regarded as a key milestone in advancing topological quantum computation in solid-state systems. Recent quantum…
Fractons from covariant higher-rank 3D BF theory
Erica Bertolini, Alberto Blasi, Matteo Carrega +2
In this paper we study the 3D gauge theory of two tensor gauge fields: , which we take symmetric, and , with no symmetry on its indices. The corresponding inv…
