Quantum advantage unlocked: Charging quantum batteries with K-regular graph stabilizers
Debkanta Ghosh, Tanoy Kanti Konar, Gianluca Francica +2
Regular graphs find broad applications ranging from quantum communication to quantum computation. Motivated by this, we investigate the design of a quantum battery based on a K-reg…
Quantum advantage from negativity of a work quasiprobability distribution
Gianluca Francica
Quantum batteries can be charged by performing a work ``instantaneously'' in the limit of a large number of cells, achieving a so-called quantum advantage. In general, the work exh…
Resource theories with completely passive states and passive states as free states
Gianluca Francica
Work extractable from quantum system can be viewed as a resource to perform some tasks. Here, we try to related the work extractable to some resource theory. To do this, we conside…
Quantum advantage in batteries for Sachdev-Ye-Kitaev interactions
Gianluca Francica
A quantum advantage can be achieved in the unitary charging of quantum batteries if their cells are interacting. Here, we try to clarify with some analytical calculations whether a…
Role of quantum correlations in daemonic expected utility
Gianluca Francica, Luca Dell'Anna
Fluctuations can challenge the possibility of improving work extraction from quantum correlations. This uncertainty in the work extraction process can be addressed resorting to the…
Work fluctuation theorems with initial quantum coherence
Gianluca Francica, Luca Dell'Anna
Fluctuation theorems are fundamental results in nonequilibrium thermodynamics beyond the linear response regime. Among these, the paradigmatic Tasaki-Crooks fluctuation theorem rel…
Optimal work extraction from quantum batteries based on the expected utility hypothesis
Gianluca Francica, Luca Dell'Anna
Work extraction in quantum finite systems is an important issue in quantum thermodynamics. The optimal work extracted is called ergotropy, and it is achieved by maximizing the aver…
Fluctuation theorems and expected utility hypothesis
Gianluca Francica, Luca Dell'Anna
The expected utility hypothesis is a popular concept in economics that is useful for making decisions when the payoff is uncertain. In this paper, we investigate the implications o…

In this short note we discuss the time-reversal of a quasiprobability distribution of work.
Normal and superconducting currents through the Sachdev-Ye-Kitaev model
Gianluca Francica, Marco Uguccioni, Luca Dell'Anna
We study the current driven by an applied voltage as a function of time through the Sachdev-Ye-Kitaev model when coupled to two normal or superconducting reservoirs. For normal lea…

Gianluca Francica, Luca Dell'Anna
We study the role of the interaction range on the Hilbert space fragmentation and many-body scar states considering a spin-1/2 many-body Hamiltonian describing a generalized Fredki…
Quasiprobability distribution of work in the quantum Ising model
Gianluca Francica, Luca Dell'Anna
A complete understanding of the statistics of the work done by quenching a parameter of a quantum many-body system is still lacking in the presence of an initial quantum coherence…
Topological phases in the presence of disorder and longer-range couplings
Gianluca Francica, Edoardo Maria Tiburzi, Luca Dell'Anna
We study the combined effects of disorder and range of the couplings on the phase diagram of one-dimensional topological superconductors. We consider an extended version of the Kit…

How to give a statistical description of thermodynamics in quantum systems is an open fundamental question. Concerning the work, the presence of initial quantum coherence in the en…
Causal games of work extraction with indefinite causal order
Gianluca Francica
An indefinite causal order, where the causes of events are not necessarily in past events, is predicted by the process matrix framework. A fundamental question is how these non-sep…
Anomalous universal adiabatic dynamics: The case of the Fredkin model
Gianluca Francica, Luca Dell'Anna
When a system is driven across a second-order quantum phase transition, the number of defects which are produced scales with the speed of the variation of the tuning parameter acco…
