Heat transport in driven quantum systems: Comparison between the Floquet-Redfield equation and the master equation in the instantaneous eigenbasis
Luca Magazzù, Christoforus Dimas Satrya, Aleksandr S. Strelnikov +2
We provide a comprehensive study of heat transport in periodically driven quantum systems using a master equation approach in the Floquet basis. Starting from the exact, formal exp…
Impact of Nonlinearities on Local Kinetic and Thermokinetic Uncertainty Relations in Bosonic Transport
Didrik Palmqvist, Luca Magazzù, Milena Grifoni +1
The precision of transport observables can be bounded by the entropy production and the activity of the transport process via kinetic and thermokinetic uncertainty relations. In li…
Heat measurement of quantum interference
Christoforus Dimas Satrya, Aleksandr S. Strelnikov, Luca Magazzù +5
Coherence is a key property of quantum systems, and it plays a central role in the operation and performance of quantum heat engines and refrigerators. Despite its importance for t…
Thermal rectification in a qubit-resonator system
Luca Magazzù, Elisabetta Paladino, Jukka P. Pekola +1
A qubit-oscillator junction connecting as a series two bosonic heat baths at different temperatures can display heat valve and diode effects. In particular, the rectification can c…
Heat transport in the quantum Rabi model: Universality and ultrastrong coupling effects
L. Magazzù, E. Paladino, M. Grifoni
Heat transport in the quantum Rabi model at weak interaction with the heat baths is controlled by the qubit-oscillator coupling. Universality of the linear conductance versus the t…

We apply the Nakajima-Zwanzig approach to open quantum systems to study steady-state transport across generic multi-level junctions coupled to bosonic or fermionic reservoirs. The…

We calculate the transmission spectra of a flux qubit coupled to a dissipative resonator in the ultrastrong coupling regime. Such a qubit-oscillator system constitutes the building…
Asymptotic Floquet states of a periodically driven spin-boson system in the nonperturbative coupling regime
L. Magazzù, S. Denisov, P. Hänggi
As a paradigmatic model of open quantum system, the spin-boson model is widely used in theoretical and experimental investigations. Beyond the weak coupling limit, the spin dynamic…
Generation and stabilization of Bell states via repeated projective measurements on a driven ancilla qubit
L. Magazzù, J. D. Jaramillo, P. Talkner +1
A protocol is proposed to generate Bell states in two non-directly interacting qubits by means of repeated measurements of the state of a central ancilla connected to both qubits.…

Probing the strongly driven spin-boson model in a superconducting quantum circuit
L. Magazzù, P. Forn-Díaz, R. Belyansky +6
Quantum two-level systems interacting with the surroundings are ubiquitous in nature. The interaction suppresses quantum coherence and forces the system towards a steady state. Suc…
