Lattice-based equation of state with a critical point from constant entropy contours and its comparison to effective QCD approaches
Hitansh Shah, Mauricio Hippert, Jorge Noronha +2
In this work, we systematically assess the performance of a new method from [H. Shah et al., Phys. Rev. C 113, L012201] for locating the QCD critical point using constant-entropy c…
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…
Scale dependence improvement of the quartic scalar field thermal effective potential in the optimized perturbation theory
Lucas G. Câmara, Marcus Benghi Pinto, Rudnei O. Ramos
Perturbation theory, as well as most thermal field resummation methods widely used to study finite-temperature quantum field theories, presents a non-negligible renormalization sca…

Speed of sound peak in isospin QCD: a natural prediction of the Medium Separation Scheme
Bruno S. Lopes, Dyana C. Duarte, Ricardo L. S. Farias +1
We present predictions for the zero-temperature equation of state at finite isospin density using the Nambu-Jona-Lasinio (NJL) model within the medium separation scheme (MSS) -- a…
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…
Chiral symmetry breaking and pion condensation in the early universe
Osvaldo Ferreira, Eduardo S. Fraga, Maurício Hippert +1
We determine the possible trajectories the universe may have followed in the QCD phase diagram during the QCD epoch. We focus on the roles of chiral symmetry breaking and pion cond…
Viability of warm inflation with standard model interactions
Rudnei O. Ramos, Gabriel S. Rodrigues
The minimal warm inflation scenario proposed in Ref. [1] -- featuring an axionlike inflaton coupled to Standard Model (SM) gluons via the standard interaction -- offe…
Warm multi natural inflation
Asuka Ito, Rudnei O. Ramos
Multi-natural inflation is studied in the context of warm inflation. We study the warm multi-natural inflation scenario with both linear and cubic temperature-dependent dissipation…
Thermal effects on warm chromoinflation
Vahid Kamali, Rudnei O. Ramos
We explore a model of a pseudo-Nambu-Goldstone boson inflaton field coupled to a non-Abelian gauge field. This model naturally leads to a warm inflation scenario, where the…
Locating the QCD critical point through contours of constant entropy density
Hitansh Shah, Mauricio Hippert, Jorge Noronha +2
We propose a new method to investigate the existence and location of the conjectured high-temperature critical point of strongly interacting matter via contours of constant entropy…

Everlyn Martins, Y. M. P. Gomes, Marcus Benghi Pinto +1
It is known that the Fierz identities predict that the Gross-Neveu and Thirring models should be equivalent when describing systems composed of a single fermionic flavor, . He…
