Non-Hermitian entropy production from fluctuation theorems
Vasco Cavina, Frank Ernesto Quintela Rodríguez, Donato Farina
We develop a first-principles thermodynamic framework for non-Hermitian dynamics based on a post-selected version of the fluctuation theorem. This allows us to identify a quantity…
Parallel ergotropy: Maximum work extraction via parallel local unitary operations
Riccardo Castellano, Ranieri Nery, Kyrylo Simonov +1
Maximum quantum work extraction is generally defined in terms of the ergotropy functional, no matter how experimentally complicated is the implementation of the optimal unitary all…
Extended local ergotropy
Riccardo Castellano, Donato Farina, Vittorio Giovannetti +1
A fundamental problem in quantum thermodynamics is to properly quantify the work extractable from out-of-equilibrium systems. While for closed systems, maximum quantum work extract…
Certification of quantum state functions under partial information
Leonardo Zambrano, Donato Farina, Egle Pagliaro +2
Convex functions of quantum states play a key role in quantum physics, with examples ranging from Bell inequalities to von Neumann entropy. However, in experimental scenarios, dire…
Recovering complete positivity of non-Markovian quantum dynamics with Choi-proximity regularization
Antonio D'Abbruzzo, Donato Farina, Vittorio Giovannetti
A relevant problem in the theory of open quantum systems is the lack of complete positivity of dynamical maps obtained after weak-coupling approximations, a famous example being th…
Thermodynamic precision in the nonequilibrium exchange scenario
Donato Farina, Bilal Benazout, Federico Centrone +1
We discuss exchange scenario's thermodynamic uncertainty relations for the work done on a two-qubit entangled nonequilibrium steady state obtained by coupling the two qubits and pu…
Ancillary Gaussian modes activate the potential to witness non-Markovianity
Dario De Santis, Donato Farina, Mohammad Mehboudi +1
We study how the number of employed modes impacts the ability to witness non-Markovian evolutions via correlation backflows in continuous-variable quantum dynamics. We first prove…
Noise-assisted and monitoring-enhanced quantum bath tagging
Donato Farina, Vasco Cavina, Marco G. Genoni +1
We analyze the capability of discriminating the statistical nature of a thermal bath by exploiting the interaction with an additional environment. We first shows that, at differenc…
Lattice-Shifted Nematic Quantum Critical Point in FeSeS
S. Chibani, D. Farina, P. Massat +13
We report the evolution of nematic fluctuations in FeSeS single crystals as a function of Sulfur content across the nematic quantum critical point (QCP) 0…
Discrimination of thermal baths by single qubit probes
Ilaria Gianani, Donato Farina, Marco Barbieri +3
Non-equilibrium states of quantum systems in contact with thermal baths help telling environments with different temperatures or different statistics apart. We extend these studies…
Going beyond Local and Global approaches for localized thermal dissipation
Donato Farina, Giulio De Filippis, Vittorio Cataudella +2
Identifying which master equation is preferable for the description of a multipartite open quantum system is not trivial and has led in the recent years to the local vs. global deb…
Quantum bath statistics tagging
Donato Farina, Vasco Cavina, Vittorio Giovannetti
The possibility of discriminating the statistics of a thermal bath using indirect measurements performed on quantum probes is presented. The scheme relies on the fact that, when we…
Open Quantum System Dynamics: recovering positivity of the Redfield equation via Partial-Secular Approximation
Donato Farina, Vittorio Giovannetti
We show how to recover complete positivity (and hence positivity) of the Redfield equation via a coarse grain average technique. We derive general bounds for the coarse graining ti…
Charger-mediated energy transfer for quantum batteries: an open system approach
Donato Farina, Gian Marcello Andolina, Andrea Mari +2
The energy charging of a quantum battery is analyzed in an open quantum setting, where the interaction between the battery element and the external power source is mediated by an a…
Charger-mediated energy transfer in exactly-solvable models for quantum batteries
Gian Marcello Andolina, Donato Farina, Andrea Mari +3
We present a systematic analysis and classification of several models of quantum batteries involving different combinations of two level systems and quantum harmonic oscillators. I…
Charge induced nematicity in FeSe
P. Massat, D. Farina, I. Paul +10
The spontaneous appearance of nematicity, a state of matter that breaks rotation but not translation symmetry, is one of the most intriguing property of the iron based superconduct…
