Operational quasiprobability formulation of non-signaling in time for macrorealism violations
Stefano Gherardini, Paolo Solinas
In this paper, we introduce the concept of quasi non-signaling in time (QNSIT), which extends non-signaling in time (NSIT) to quasiprobability distributions. QNSIT requires that th…
Reverse engineering of mechano-kinetic parameters from stochastic force profiles in heterogeneous ensembles of molecular motors and tracks
Valentina Buonfiglio, Irene Pertici, Pasquale Bianco +2
Heterogeneity in contractile systems of molecular motors interacting with their tracks plays a key role in numerous cellular physiological and pathological processes. However, its…
Macroscopic Fokker-Planck equation from microscopic Glauber dynamics for the Nagle-Kardar model
Jean-François de Kemmeter, Stefano Ruffo, Stefano Gherardini
In the companion Letter we have highlighted the dynamical universality class of the Nagle-Kardar model, where a mean-field interaction is added to the one-dimensional nearest-neigh…
Quantum work statistics and coherence effects in quenched bosonic Josephson junctions
Mattia Orlandini, Stefano Gherardini, Lorenzo Buffoni +1
We investigate the non-equilibrium work statistics originating from a sudden quench in a bosonic Josephson junction. In particular, by employing the Holstein-Primakoff approximatio…
Revealing the topology of quantum states via Kirkwood-Dirac quasiprobabilities
Stefano Gherardini, Luca Lepori
We discuss a theoretical approach to discriminate whether two states of a many-body quantum system belong or not to different topology classes. This approach is based on expressing…
Nonclassical energy-change distribution as a witness of non-Markovian quantum dynamics
Marco Pezzutto, Anton Corr, Gabriele De Chiara +2
We address the problem of identifying non-Markovian quantum time evolutions of an open quantum system by only performing measurements of the system's energy. We demonstrate that vi…
Squeezing and adiabaticity breaking in time-dependent quantum harmonic oscillators
Mattia Orlandini, Beatrice Donelli, Lorenzo Buffoni +1
The quantum harmonic oscillator with time-dependent frequency is a paradigmatic model of driven quantum dynamics and one of the few nontrivial systems that admits an exact analytic…
Operational criterion for Wigner function negativity
Paolo Solinas, Beatrice Donelli, Stefano Gherardini
We introduce an operational criterion to identify Wigner function (WF) negativity for an arbitrary quantum state within the framework of quantum non-demolition measurements. This c…
Ising Models of Cooperativity in Muscle Contraction
Elaheh Saadat, Matthieu Caruel, Stefano Gherardini +6
Regulation of contraction in striated muscle is controlled by a dual mechanism involving both thin filaments containing actin and thick filaments containing myosin. The thin filame…
Experimental challenges and prospects for quantum-enhanced energy conversion: Stationary Fano coherence in V-type qutrits interacting with polarized incoherent radiation
Ludovica Donati, Francesco Saverio Cataliotti, Stefano Gherardini
Quantum coherence offers potential for energy conversion technologies. It influences light absorption and emission, affecting energy conversion limits and efficiency. As a result,…
