Smart Walkers in Discrete Space
Gianluca Peri, Lorenzo Buffoni, Giacomo Chiti +4
We study the statistical properties of trainable agents moving in discrete space. After introducing the mathematical framework, we first analyze the dynamics of two completely rand…
Generalized Landauer bound from absolute irreversibility
Lorenzo Buffoni, Francesco Coghi, Stefano Gherardini
In this work, we introduce a generalization of the Landauer bound for erasure processes that stems from absolutely irreversible dynamics. Assuming that the erasure process is carri…
Convergence of the Integral Fluctuation Theorem estimator for nonequilibrium Markov systems
Francesco Coghi, Lorenzo Buffoni, Stefano Gherardini
The Integral Fluctuation Theorem for entropy production (IFT) is among the few equalities that are known to be valid for physical systems arbitrarily driven far from equilibrium. M…
Spontaneous fluctuation-symmetry breaking and the Landauer principle
Lorenzo Buffoni, Michele Campisi
We study the problem of the energetic cost of information erasure by looking at it through the lens of the Jarzynski equality. We observe that the Landauer bound, $\langle W \rangl…
Improved bound on entropy production in a quantum annealer
Michele Campisi, Lorenzo Buffoni
For a system described by a multivariate probability density function obeying the fluctuation theorem, the average dissipation is lower-bounded by the degree of asymmetry of the ma…
Quantum Measurement Cooling
Lorenzo Buffoni, Andrea Solfanelli, Paola Verrucchi +2
Invasiveness of quantum measurements is a genuinely quantum mechanical feature that is not necessarily detrimental: Here we show how quantum measurements can be used to fuel a cool…
