A Dual-Species Bose-Einstein Condensate with Attractive Interspecies Interactions
(MDPI, 2020-03-21)We report on the production of a 41 K- 87 Rb dual-species Bose–Einstein condensate with tunable interspecies interaction and we study the mixture in the attractive regime; i.e., for negative values of the interspecies ... -
Effect of Interactions in the Interference Pattern of Bose-Einstein Condensates
(American Physical Society, 2020-10-12)Understanding the effect of interactions in the phase evolution of expanding atomic Bose-Einstein condensates is fundamental to describing the basic phenomenon of matter wave interference. Many theoretical and experimental ... -
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, ... -
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 ... -
Measurement-induced, spatially-extended entanglement in a hot, strongly-interacting atomic system
(Nature, 2020-05-15)Quantum technologies use entanglement to outperform classical technologies, and often employ strong cooling and isolation to protect entangled entities from decoherence by random interactions. Here we show that the opposite ... -
Noncollinearity in dijet fragmentation in electron-positron scattering
(American Physical Society, 2019-08-09)We study fragmentation in electron-positron annihilation assuming a dijet situation, using variables defined independent of any frame. In a collinear situation some of the variables are centered around zero with the small ... -
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 ... -
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 ... -
Thermodynamics of Resonant Scalars in AdS/CFT and implications for QCD
(E. D. P Sciences, 2016)We explore the thermodynamics of a simple 5D Einstein-dilaton gravity model with a massive scalar field, with asymptotically AdS behavior in the UV. The holographic renormalization is addressed in details, and analytical ... -
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 ... -
Update of inclusive cross sections of single and pairs of identified light charged hadrons
(American Physical Society, 2020-05-13)We report new measurements of the production cross sections of pairs of charged pions and kaons as a function of their fractional energies using various fractional-energy definitions. Two different fractional-energy ...
