Null test for interactions in the dark sector
Rodrigo von Marttens, Valerio Marra, Luciano Casarini +2
Since there is no known symmetry in Nature that prevents a non-minimal coupling between the dark energy (DE) and cold dark matter (CDM) components, such a possibility constitutes a…
J-PLUS: Identification of low-metallicity stars with artificial neural networks using SPHINX
D. D. Whitten, V. M. Placco, T. C. Beers +24
We present a new methodology for the estimation of stellar atmospheric parameters from narrow- and intermediate-band photometry of the Javalambre Photometric Local Universe Survey…
J-PLUS: analysis of the intracluster light in the Coma cluster
Y. Jiménez-Teja, R. A. Dupke, R. Lopes de Oliveira +19
The intracluster light (ICL) is a luminous component of galaxy clusters composed of stars that are gravitationally bound to the cluster potential but do not belong to the individua…
Disorder-safe entanglement transfer through ladder qubit chains
Guilherme M. A. Almeida, Andre M. C. Souza, Francisco +3
We study an entanglement transfer protocol in a two-leg ladder spin-1/2 chain in the presence of disorder. In the regime where on-site energies and the intrachain couplings follow…
Physical constraints on interacting dark energy models
J. E. Gonzalez, H. H. B. Silva, R. Silva +1
Physical limits on the equation-of-state (EoS) parameter of a dark energy component non-minimally coupled with the dark matter field are examined in light of the second law of ther…
Optical remote control of a charge qubit
Ted S. Santana, Francisco A. G. Almeida
Both the electron transport-based qubits, implemented through double quantum dots, and the sources of indistinguishable single-photons like self-assembled quantum dots are strong c…
