Twisted Gaussian Schell States in Quantum Optics: Twist-Assisted Nonclassicality and Entanglement

Fabricio Toscano, G. Cañas, A. Z. Khoury +2

We introduce the Twisted Gaussian Schell (TGS) state, a two-mode mixed Gaussian state defined as the quantum-optical analog of the Twisted Gaussian Schell-model beam of classical p…

Thermal equilibrium in Gaussian dynamical semigroups

Fabricio Toscano, Fernando Nicacio

We characterize all Gaussian dynamical semigroups in continuous variables quantum systems of n-bosonic modes which have a thermal Gibbs state as a stationary solution. This is perf…

Fluctuation and dissipation in memoryless open quantum evolutions

Fabricio Toscano, Gustavo M. Bosyk, Steeve Zozor +1

Von Neumann entropy rate for open quantum systems is, in general, written in terms of entropy production and entropy flow rates, encompassing the second law of thermodynamics. When…

Work statistics for sudden quenches in interacting quantum many-body systems

Eric G. Arrais, Diego A. Wisniacki, Augusto J. Roncaglia +1

Work in isolated quantum systems is a random variable and its probability distribution function obeys the celebrated fluctuation theorems of Crooks and Jarzynski. In this study, we…

Uncertainty Relations for coarse-grained measurements: an overview

Fabricio Toscano, Daniel S. Tasca, Łukasz Rudnicki +1

Uncertainty relations involving complementary observables are one of the cornerstones of quantum mechanics. Aside from their fundamental significance, they play an important role i…

Quantum work for sudden quenches in Gaussian random Hamiltonians

Eric G. Arrais, Diego A. Wisniacki, Lucas C. Céleri +3

In the context of nonequilibrium quantum thermodynamics, variables like work behave stochastically. A particular definition of the work probability density function (pdf) for coher…
