Quantum advantage bounds for a multipartite Gaussian battery
F. Cavaliere, D. Ferraro, M. Carrega +2
We demonstrate the possibility of a genuine quantum advantage in the efficiency of quantum batteries by analyzing a model that enables a consistent comparison between quantum and c…
Work extraction from a quantum battery charged through an array of coupled cavities
I. Beder, D. Ferraro, P. A. Brandão
We investigate the problem of work extraction from a cavity-based quantum battery that is remotely charged via a transmission line composed of an array of coupled single-mode cavit…
Enhanced shot noise in graphene quantum point contacts with electrostatic reconstruction
M. Garg, O. Maillet, N. L. Samuelson +13
Shot noise measurements in quantum point contacts are a powerful tool to investigate charge transport in the integer and fractional quantum Hall regime, in particular to unveil the…
Hybrid interacting quantum Hall thermal machine
S. Finocchiaro, D. Ferraro, M. Sassetti +1
We investigate a hybrid thermal machine based on a single closed quantum Hall edge channel forming a quantum dot. It is tunneling coupled with two quantum Hall states at in…
