Thermoelectric properties of an interacting quantum dot-based heat engine
Paolo Andrea Erdman, Francesco Mazza, Riccardo Bosisio +3
We study the thermoelectric properties and heat-to-work conversion performance of an interacting, multi-level quantum dot (QD) weakly coupled to electronic reservoirs. We focus on…
Thermoelectric Effects in Nanowire-Based MOSFETs
Riccardo Bosisio, Geneviève Fleury, Cosimo Gorini +1
We review a series of works describing thermoelectric effects in gated disordered nanowires (field effect transistor device configuration). After considering the elastic coherent r…
A Microwave Josephson Refrigerator
Paolo Solinas, Riccardo Bosisio, Francesco Giazotto
We present a microwave quantum refrigeration principle based on the Josephson effect. When a superconducting quantum interference device (SQUID) is pierced by a time-dependent magn…
Negative differential thermal conductance and heat amplification in superconducting hybrid devices
Antonio Fornieri, Giuliano Timossi, Riccardo Bosisio +2
We investigate the thermal transport properties of a temperature-biased Josephson tunnel junction composed of two different superconductors. We show that this simple system can pro…
Nanowire-based thermoelectric ratchet in the hopping regime
Riccardo Bosisio, Geneviève Fleury, Jean-Louis Pichard +1
We study a thermoelectric ratchet consisting of an array of disordered nanowires arranged in parallel on top of an insulating substrate, and contacted asymmetrically to two electro…
Absorbing/Emitting Phonons with one dimensional MOSFETs
Riccardo Bosisio, Cosimo Gorini, Geneviève Fleury +1
We consider nanowires in the field effect transistor device configuration. Modeling each nanowire as a one dimensional lattice with random site potentials, we study the heat exchan…
Nanoscale phase-engineering of thermal transport with a Josephson heat modulator
Antonio Fornieri, Christophe Blanc, Riccardo Bosisio +2
Macroscopic quantum phase coherence has one of its pivotal expressions in the Josephson effect [1], which manifests itself both in charge [2] and energy transport [3-5]. The abilit…
A magnetic thermal switch for heat management at the nanoscale
Riccardo Bosisio, Stefano Valentini, Francesco Mazza +4
In a multi-terminal setup, when time-reversal symmetry is broken by a magnetic field, the heat flows can be managed by designing a device with programmable Boolean behavior. We sho…
Parasitic effects in SQUID-based radiation comb generators
Riccardo Bosisio, Francesco Giazotto, Paolo Solinas
We study several parasitic effects on the implementation of a Josephson radiation comb generator (JRCG) based on a dc superconducting quantum interference device (SQUID) driven by…
Separation of heat and charge currents for boosted thermoelectric conversion
Francesco Mazza, Stefano Valentini, Riccardo Bosisio +4
In a multi-terminal device the (electronic) heat and charge currents can follow different paths. In this paper we introduce and analyse a class of multi-terminal devices where this…
Radiation comb generation with extended Josephson junctions
P. Solinas, R. Bosisio, F. Giazotto
We propose the implementation of a Josephson radiation comb generator (JRCG) based on an extended Josephson junction subject to a time dependent magnetic field. The junction critic…
Using Activated Transport in Parallel Nanowires for Energy Harvesting and Hot Spot Cooling
Riccardo Bosisio, Cosimo Gorini, Geneviève Fleury +1
We study arrays of parallel doped semiconductor nanowires in a temperature range where the electrons propagate through the nanowires by phonon assisted hops between localized state…
Thermoelectric efficiency of three-terminal quantum thermal machines
Francesco Mazza, Riccardo Bosisio, Giuliano Benenti +3
The efficiency of a thermal engine working in linear response regime in a multi-terminals configuration is discussed. For the generic three-terminal case, we provide a general defi…
Gate-modulated thermopower of disordered nanowires: II. Variable-range hopping regime
Riccardo Bosisio, Cosimo Gorini, Geneviève Fleury +1
We study the thermopower of a disordered nanowire in the field effect transistor configuration. After a first paper devoted to the elastic coherent regime (Bosisio R., Fleury G. an…
Gate-modulated thermopower in disordered nanowires: I. Low temperature coherent regime
Riccardo Bosisio, Geneviève Fleury, Jean-Louis Pichard
Using a one-dimensional tight-binding Anderson model, we study a disordered nanowire in the presence of an external gate which can be used for depleting its carrier density (field…
Validity of the Wiedemann-Franz law in small molecular wires
Vinitha Balachandran, Riccardo Bosisio, Giuliano Benenti
We report our investigations on the finite-size effects of the Lorenz number in a molecular wire. Using Landauer-Büttiker formalism, we find that for sufficiently long wires there…
