Bipolar Thermoelectric Superconducting Quantum Devices
F. Antola, G. Marchegiani, A. Braggio +1
Quantum technologies increasingly require accurate modeling of their hardware components and of the non-equilibrium regimes in which they operate, where managing heat and energy fl…
Subgap Linear Thermoelectricity in Superconducting Quantum Hall Systems
Leonardo Pierattelli, Fabio Taddei, Alessandro Romito +1
We show that an integer quantum Hall setup proximized by superconductors can exhibit subgap thermoelectric effects in the linear-response regime when triplet superconducting correl…
Nonequilibrium Cooper quartet generation in superconducting devices
Luca Chirolli, Alessandro Braggio, Michele Governale
Cooper quartets are aggregates of four electrons that generalize the concept of Cooper pairs, and their study can unfold unexplored perspectives in correlated matter and many-body…
Magnetically Induced Switching-Current Jumps in InAs/Al Josephson Junctions
Ofelia Durante, Roberta Citro, Elia Strambini +8
We report Barkhausen-like switching at millitesla fields in an -doped InAs/Al nanowire Josephson junction, which serves as an interferometric probe of intrinsic magnetic reconfi…
Enhanced Thermoelectricity in Nanowires with inhomogeneous Helical states
Zahra Aslani, Fabio Taddei, Fabrizio Dolcini +1
Semiconductor nanowires (NWs) with strong Rashba spin-orbit coupling (RSOC), when exposed to a suitably applied Zeeman field, exhibit one-dimensional helical channels with a spin o…
Quantum Bipolar Thermoelectricity
Filippo Antola, Giorgio De Simoni, Francesco Giazotto +1
Thermoelectricity is generally understood as a classical effect emerging from energy-dependent transport asymmetries. Here we uncover a purely quantum mechanism, where a supercondu…
