Unfolding of antiferromagnetic phases and multicritical points in a two-orbital model for uranium compounds under pressure and magnetic field
(2020) [Journal article]We investigate the occurrence of multicritical points under pressure and magnetic field in a model that describes two 5 f bands (of either α or β characters), which hybridize with a single itinerant conduction band. The 5 ... -
Search for top squark pair production in a final state with two tau leptons in proton-proton collisions at √s = 13 TeV
(2020) [Journal article]A search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at √ s = 13 TeV is presented in a final state containing hadronically decaying tau leptons and ... -
Active galactic nuclei winds as the origin of the H2 emission excess in nearby galaxies
(2020) [Journal article]In most galaxies, the fluxes of rotational H2 lines strongly correlate with star formation diagnostics [such as polycyclic aromatic hydrocarbons (PAHs)], suggesting that H2 emission from warm molecular gas is a minor ... -
Combined search for supersymmetry with photons in proton-proton collisions at √s=13 TeV
(2020) [Journal article]A combination of four searches for new physics involving signatures with at least one photon and large missing transverse momentum, motivated by generalized models of gauge-mediated supersymmetry(SUSY) breaking, is presented. ... -
Nanoscale density fluctuations in swift heavy ion irradiated amorphous SiO2
(2011) [Journal article]We report on the observation of nanoscale density fluctuations in 2 μm thick amorphous SiO2 layers irradiated with 185 MeV Au ions. At high fluences, in excess of approximately 5 1012 ions=cm², where the surface is completely ... -
Observation of nuclear modifications in W± boson production in pPb collisions at √snn = 8.16 TeV
(2020) [Journal article]The production of W± bosons is studied in proton-lead (pPb) collisions at a nucleon-nucleon centre-of-mass energy of √snn = 8.16 TeV. Measurements are performed in the W± → μ±vμ channel using a data sample corresponding ... -
Multiplicity dependence of light (anti-)nuclei production in p–Pb collisions at √snn = 5.02 TeV
(2020) [Journal article]The measurement of the deuteron and anti-deuteron production in the rapidity range -1 < y < 0 as a function of transverse momentum and event multiplicity in p–Pb collisions at √snn = 5.02 TeV is presented. (Anti-)deuterons ... -
Phase transitions in atypical systems induced by a condensation transition on graphs
(2020) [Journal article]Random graphs undergo structural phase transitions that are crucial for dynamical processes and cooperative behavior of models defined on graphs. In this work we investigate the impact of a first-order structural transition ... -
Dynamical cluster size heterogeneity
(2020) [Journal article]Only recently has the essential role of the percolation critical point been considered on the dynamical properties of connected regions of aligned spins (domains) after a sudden temperature quench. In equilibrium, it is ... -
Liderança e gênero em um debate acadêmico entre graduandos em física
(2010) [Journal article]A presente pesquisa buscou investigar a construção de lideranças na dinâmica discursiva de um debate sobre Mecânica Quântica entre estudantes de um curso de graduação em Física e possíveis relações com as diferenças de ...
