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 ...
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 ...
Nonperturbative dynamical decoupling with random control
(Nature Publishing Group, 2014-08-29)
Parametric fluctuations or stochastic signals are introduced into the rectangular pulse sequence to investigate the feasibility of random dynamical decoupling. In a large parameter region, we find that the out-of-order ...
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, ...
Spatial-temporal excess mortality patterns of the 1918-1919 influenza pandemic in Spain
(Biomed Central, 2014-07-05)
Background: The impact of socio-demographic factors and baseline health on the mortality burden of seasonal and pandemic influenza remains debated. Here we analyzed the spatial-temporal mortality patterns of the 1918 ...
Possible antigravity regions in F (R) theory?
(Elsevier, 2014-03-07)
We construct an F(R) gravity theory corresponding to the Weyl invariant two scalar field theory. We investigate whether such F (R) gravity can have the antigravity regions where the Weyl curvature invariant does not diverge ...
Transverse target single-spin asymmetry in inclusive electroproduction of charged pions and kaons
(Elsevier, 2014-01-20)
Single-spin asymmetries were investigated in inclusive electroproduction of charged pions and kaons from transversely polarized protons at the HERMES experiment. The asymmetries were studied as a function of the azimuthal ...
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 ...
