Permutationally invariant state reconstruction
(IOP Publishing, 2012-10)
Feasible tomography schemes for large particle numbers must possess, besides an appropriate data acquisition protocol, an efficient way to reconstruct the density operator from the observed finite data set. Since state ...
Entanglement negativity in the harmonic chain out of equilibrium
(IOP Publishing, 2014-12-08)
We study the entanglement in a chain of harmonic oscillators driven out of equilibrium by preparing the two sides of the system at different temperatures, and subsequently joining them together. The steady state is constructed ...
Energy and momentum transfer in one-dimensional trapped gases by stimulated light scattering
(IOP Publishing, 2015-06-10)
In ultracold atoms settings, inelastic light scattering is a preeminent technique to reveal static and dynamic properties at nonzero momentum. In this work, we investigate an array of one-dimensional trapped Bose gases, ...
A formalism based on moments for classical and quantum cosmology
(IOP Publishing LTD, 2015)
We compare the classical and quantum description of systems with one degree of freedom with an effective formalism based on statistical moments. Within this formalism the similarities and differences between the classical ...
Subdiffusion of nonlinear waves in quasiperiodic potentials
(IOP Publishing, 2012-10-23)
We study the time evolution of wave packets in one-dimensional quasiperiodic lattices which localize linear waves. Nonlinearity (related to two-body interactions) has a destructive effect on localization, as observed ...
Black Holes, Cosmological Solutions, Future Singularities, and Their Thermodynamical Properties in Modified Gravity Theorie
(MDPI, 2012-09-18)
Along this review, we focus on the study of several properties of modified
gravity theories, in particular on black-hole solutions and its comparison with those solutions in General Relativity, and on Friedmann–Lemaˆıtr ...
The center of mass and center of charge of the electron
(IOP Publishing, 2015)
The goal of this contribution is to show that the hypothesis that the center of mass(CM) and the center of charge(CC) of a classical electron are two different points is only compatible with a relativistic description. The ...
Calibrating Analytical Models for Semilocal Strings
(IOP Publishing, 2015)
In this work we calibrate two different analytic models of semilocal strings by constraining the values of their free parameters. In order to do so, we use data obtained from the largest and most accurate field theory ...
Cosmological constrains on fast transition Unified Dark Matter models
(IOP Publishing, 2015)
In this work we show the results obtained applying a Unified Dark Matter (UDM) model with a fast transition to a set of cosmological data. Two different functions to model the transition are tested, and the feasibility of ...
Entanglement and extreme spin squeezing of unpolarized states
(IOP Publishing, 2017-01-20)
We present criteria to detect the depth of entanglement in macroscopic ensembles of spin-j particles using the variance and second moments of the collective spin components. The class of states detected goes beyond traditional ...
