Charged-particle multiplicity fluctuations in Pb–Pb collisions at √sNN = 2.76 TeV
(2021) [Artigo de periódico]Measurements of event-by-event fluctuations of charged-particle multiplicities in Pb–Pb collisions at √sNN = 2.76 TeV using the ALICE detector at the CERN Large Hadron Collider (LHC) are presented in the pseudorapidity ... -
Coarse-grained models of stripe forming systems : phase diagrams, anomalies, and scaling hypothesis
(2012) [Artigo de periódico]Two coarse-grained models which capture some universal characteristics of stripe forming systems are studied. At high temperatures, the structure factors of both models attain their maxima on a circle in reciprocal space, ... -
Conductance fluctuations in high mobility monolayer graphene : nonergodicity, lack of determinism and chaotic behavior
(2016) [Artigo de periódico]We have fabricated a high mobility device, composed of a monolayer graphene flake sandwiched between two sheets of hexagonal boron nitride. Conductance fluctuations as functions of a back gate voltage and magnetic field ... -
Effects of geometric constraints on the nuclear multifragmentation process
(2007) [Artigo de periódico]We include in statistical model calculations the facts that in the nuclear multifragmentation process the fragments are produced within a given volume and have a finite size. The corrections associated with these constraints ... -
Index statistical properties of sparse random graphs
(2015) [Artigo de periódico]Using the replica method, we develop an analytical approach to compute the characteristic function for the probability PN(K,λ) that a large N × N adjacency matrix of sparse random graphs has K eigenvalues below a threshold ... -
Ionospheric ion-acoustic enhancements by turbulent counterstreaming electron beam-plasma interaction
(2010) [Artigo de periódico]Ion-acoustic enhancements are investigated within the context of turbulent beam-plasma interaction processes. The analysis assumes a pair of counterstreaming electron beams interacting with the background plasma. Two-dimensional ... -

Time evolution of the extremely diluted Blume-Emery-Griffiths neulal network
(2003) [Artigo de periódico]A study of the time evolution and a stability analysis of the phases in the extremely diluted Blume-Emery-Griffiths neural network model are shown to yield new phase diagrams in which fluctuation retrieval may drive pattern ...
