Spin squeezing, macrorealism and the heisenberg uncertainty principle
(2015-10-09)
En paralelo con el desarrollo de un formalismo matemáticobien definido para la teoría cuántica [19, 48, 175], se abrióun debate sobre el sorprendente contraste entre los ¿misteriosos¿fenómenos cuánticos (incompatibilidad ...
Spin-related phenomena in magnetic and spin-orbit couppled bose-einstein condensates
(2015-06-08)
El condensado de Bose-Einstein (CBE) es uno de los primeros fenómenos predichos por la física cuántica macroscópica. El aspecto más notable de este efecto es la condensación en el espacio de momentos y no en el de coordenadas. ...
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 ...
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 ...
Monte Carlo methods for TMD analyses
(EDP Sciences, 2015)
Monte Carlo simulations are an indispensable tool in experimental high-energy physics. Indeed, many discoveries rely on realistic modeling of background processes. In the field of transverse-momentum-dependent parton ...
Recent HERMES results from inclusive and semi-inclusive hadron production
(EDP Sciences, 2015)
HERMES collected a wealth of data using the 27.6 GeV polarized HERA lepton beam and various pure, polarized and unpolarized, gaseous targets. This unique data set opens the door to various measurements sensitive to the ...
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 ...
Anisotropic expansion and SNIa: An open issue
(Elsevier, 2015-02-04)
We review the appropriateness of using SNIa observations to detect potential signatures of anisotropic expansion in the Universe. We focus on Union2 and SNLS3 SNIa datasets and use the hemispherical comparison method to ...
