The presence and order of QCD phase transitions from gravitational-wave observations of neutron star mergers
Paul D. Lasky, Alexander Clevinger, Andre G. da Silva +2
Gravitational-wave observations of neutron star mergers allows us to probe the dense portion of the nuclear equation of state. We develop a formalism for testing the existence and…
From Threshold Crossing to Wave-function Renormalization: Defining the Pion Mott Temperature in a Magnetic Field
Sidney S. Avancini, Maximo Coppola, Dyana C. Duarte +3
We investigate the dissociation of the neutral pion in hot magnetized quark matter within the two-flavor Nambu--Jona-Lasinio model. At zero magnetic field, the Mott temperature is…
Robust Finite-Momentum Instabilities in Dense Matter
André G. da Silva, Ricardo L. S. Farias, Theo Motta +1
The predicted extent of inhomogeneous chiral phases in effective models of quantum chromodynamics is notoriously sensitive to ultraviolet regularization. We show that this sensitiv…
Quantifying uncertainty in the neutron-star equation of state using point estimates and posterior distributions
André Gonçalves da Silva, Ricardo Luciano Sonego Farias
We investigate uncertainty quantification for the neutron-star equation of state (EOS) by comparing point-estimation and distributional inference approaches using the same Chebyshe…
Meson mixing effects on the speed of sound in isospin-imbalanced matter
Alejandro Ayala, Bruno S. Lopes, Ricardo L. S. Farias +1
We explore isospin imbalanced strongly interacting matter within the two-flavor Linear Sigma Model with quarks, an effective model for low-energy QCD. At one loop order, including…
Two-flavor chirally imbalanced quark matter beyond large
André G. da Silva, Dyana C. Duarte, Ricardo L. S. Farias +3
We investigate a chirally imbalanced medium in the context of the two-flavor Nambu--Jona-Lasinio model using both the large- (LN) and beyond large- (BLN) approximations.…
Speed of sound peak in two-color dense QCD: confronting effective models with lattice data
Arthur E. B. Pasqualotto, Dyana C. Duarte, Ricardo L. S. Farias +1
Lattice simulations of two-color, two-flavor Quantum Chromodynamics (QCD) at finite quark chemical potential have revealed a distinctive peak structure in the sound velocity. Altho…
Chiral and deconfinement transitions in spin-polarized quark matter
Ricardo L. S. Farias, William R. Tavares
We investigate the influence of spin polarization in strongly interacting matter by introducing a finite spin potential, , which effectively controls the spin density of the s…
Strongly interacting matter in extreme magnetic fields
Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58
Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…
Chiral vortical catalysis constrained by LQCD simulations
Rodrigo M. Nunes, Ricardo L. S. Farias, William R. Tavares +1
Evidences of vortical effects have been recently found by experiments in heavy ion collisions, instigating new insights into the phase diagram of quantum chromodynamics (QCD). Cons…
Charged scalars at finite electric field and temperature in the optimized perturbation theory
William R. Tavares, Rudnei O. Ramos, Ricardo L. S. Farias +1
We study the symmetry breaking and restoration behavior of a self-interacting charged scalar field theory under the influence of a constant electric field and finite temperature. O…
Artificial first-order phase transition in a magnetized Nambu--Jona-Lasinio model with a quark anomalous magnetic moment
William R. Tavares, Sidney S. Avancini, Ricardo L. S. Farias +1
Recently, first-order phase transitions have been predicted as an effect of the inclusion of quark anomalous magnetic moment (AMM) in the hot and magnetized Nambu--Jona-Lasinio mod…
What is the magnetic field distribution for the equation of state of magnetized neutron stars?
V. Dexheimer, B. Franzon, R. O. Gomes +3
In this Letter, we report a realistic calculation of the magnetic field profile for the equation of state inside strongly magnetized neutron stars. Unlike previous estimates, which…
