Scanning Gate Microscopy Modulation of Supercurrent in Graphene Josephson Junctions
Ivan Villani, Samuele Fracassi, Niccolò Traverso Ziani +9
The paper uses scanning gate microscopy to locally modulate and map the supercurrent in hBN‑encapsulated graphene Josephson junctions with niobium contacts, analyzing how tip volta…
Quantum Batteries in two-dimensional material-based Josephson Junctions
V. Varrica, G. Gemme, F. M. D. Pellegrino +3
We investigate the solid-state implementation of a Dicke-like quantum battery consisting of a two-dimensional material-based Josephson junction inductively coupled to a resonator,…
Confinement-induced Majorana modes in a nodal topological superconductor
Simone Traverso, Niccolò Traverso Ziani, Maura Sassetti +1
We investigate the topological phase diagram of {an extension of the Haldane model with equal spin pairing superconductivity}. In two dimensions, we find a topological nodal superc…
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…
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…
Charging free fermion quantum batteries
Riccardo Grazi, Fabio Cavaliere, Maura Sassetti +2
The performances of many-body quantum batteries strongly depend on the Hamiltonian of the battery, the initial state, and the charging protocol. In this article we derive an analyt…
