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 ...
Embedding quantum simulators
(2015-06-25)
Quantum simulations consist in the reproduction of the dynamics of a quantum systemon a controllable platform, with the goal of capturing an interesting feature of the considered model. It is broadly believed that the ...
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 ...
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 ...
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 ...
Quantum Simulator for Transport Phenomena in Fluid Flows
(Nature Publishing Group, 2015-08-17)
Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we develop a quantum simulator based on ...
Hartle's model within the general theory of perturbatiye matchings: the change in mass
(IOP Publishing, 2015)
Hartle's model provides the most widely used analytic framework to describe isolated compact bodies rotating slowly in equilibrium up to second order in perturbations in the context of General Relativity. Apart from some ...
