Non-Linear Thermovoltage in a Single-Electron Transistor
Paolo A. Erdman, Joonas T. Peltonen, Bibek Bhandari +5
We perform direct thermovoltage measurements in a single-electron transistor, using on-chip local thermometers, both in the linear and non-linear regimes. Using a model which accou…
Maximum power and corresponding efficiency for two-level heat engines and refrigerators: optimality of fast cycles
Paolo Andrea Erdman, Vasco Cavina, Rosario Fazio +2
We study how to achieve the ultimate power in the simplest, yet non trivial, model of a thermal machine, namely a two-level quantum system coupled to two thermal baths. Without mak…
Optimal probabilistic work extraction beyond the free energy difference with a single-electron device
Olivier Maillet, Paolo A. Erdman, Vasco Cavina +8
We experimentally realize protocols that allow to extract work beyond the free energy difference from a single electron transistor at the single thermodynamic trajectory level. Wit…
Manipulation of Cooper pair entanglement in hybrid topological Josephson junctions
Gianmichele Blasi, Fabio Taddei, Vittorio Giovannetti +1
In this work we investigate the supercurrent in a hybrid topological Josephson junction consisting of two planes of topological insulator (TI) in a specific configuration, which al…
Failure of conductance quantization in two-dimensional topological insulators due to non-magnetic impurities
Pietro Novelli, Fabio Taddei, Andre K. Geim +1
Despite topological protection and the absence of magnetic impurities, two-dimensional topological insulators display quantized conductance only in surprisingly short channels, whi…
Absorption refrigerators based on Coulomb-coupled single-electron systems
Paolo Andrea Erdman, Bibek Bhandari, Rosario Fazio +2
We analyze a simple implementation of an absorption refrigerator, a system that requires heat and not work to achieve refrigeration, based on two Coulomb coupled single-electron sy…
Nonlocal superconducting correlations in graphene in the quantum Hall regime
Michael Beconcini, Marco Polini, Fabio Taddei
We study Andreev processes and nonlocal transport in a three-terminal graphene-superconductor hybrid system under a quantizing perpendicular magnetic field [G.-H. Lee et al., Natur…
Thermal drag in electronic conductors
Bibek Bhandari, Giuliano Chiriacò, Paolo A. Erdman +2
We study the electronic thermal drag in two different Coulomb-coupled systems, the first one composed of two Coulomb blockaded metallic islands and the second one consisting of two…
