Magnetic catalysis and Hall conductivity of excitonic insulators in a planar four-Fermi model
William R. Tavares, Rudnei O. Ramos, Nei Lopes
We study the effects of a perpendicular magnetic field on the excitonic insulator (EI) phase in the semiconductor regime using an extended planar four-Fermi model. Within the large…
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
The paper investigates the peak in the speed of sound seen in lattice simulations of two‑color, two‑flavor QCD at finite chemical potential and shows that an NJL model enhanced wit…
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…
The early universe is -ing
Arjun Berera, Suddhasattwa Brahma, Zizang Qiu +2
The recently released data from the (ACT) confirms that the primordial scalar spectrum is extremely flat. This, together with current upper b…
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.…
