Ultra-stable charging of fast-scrambling SYK quantum batteries
Dario Rosa, Davide Rossini, Gian Marcello Andolina +2
Collective behavior strongly influences the charging dynamics of quantum batteries (QBs). Here, we study the impact of nonlocal correlations on the energy stored in a system of …
Quantum advantage in the charging process of Sachdev-Ye-Kitaev batteries
Davide Rossini, Gian Marcello Andolina, Dario Rosa +2
The exactly-solvable Sachdev-Ye-Kitaev (SYK) model has recently received considerable attention in both condensed matter and high energy physics because it describes quantum matter…
Levitons in helical liquids with Rashba spin-orbit coupling probed by a superconducting contact
Flavio Ronetti, Matteo Carrega, Maura Sassetti
We consider transport properties of a single edge of a two-dimensional topological insulators, in presence of Rashba spin-orbit coupling, driven by two external time-dependent volt…
Nonlocal Thermoelectricity in a S-TI-S Junction in Contact with a N-Metal Probe: Evidence for Helical Edge States
Gianmichele Blasi, Fabio Taddei, Liliana Arrachea +2
We consider a Josephson junction hosting a Kramers pair of helical edge states of a quantum spin Hall bar in contact with a normal-metal probe. In this hybrid system, the orbital p…
Thermodynamics of a phase-driven proximity Josephson junction
Francesco Vischi, Matteo Carrega, Alessandro Braggio +2
We study the thermodynamic properties of a superconductor/normal metal/superconductor Josephson junction {in the short limit}. Owing to the proximity effect, such a junction consti…
Investigation of InAs based devices for topological applications
Matteo Carrega, Stefano Guiducci, Andrea Iorio +10
Hybrid superconductor/semiconductor devices constitute a powerful platform to investigate the emergence of new topological state of matter. Among all possible semiconductor materia…
