Coupled nuclear and leptonic longitudinal collective modes in neutron star matter : a covariant Vlasov approach

Aziz Rabhi, Olfa Boukari, Sidney S. Avancini +1

A covariant relativistic approach based on the Vlasov equation is used to study collective modes in neutron-star matter. The analysis is carried out within relativistic mean-field…

Longitudinal collective modes in relativistic asymmetric magnetized nuclear matter within the covariant Vlasov approach

Aziz Rabhi, Olfa Boukari, Sidney S. Avancini +1

The neutron-proton-electron (npe) matter under strong magnetic field is studied in the context of the covariant Vlasov approach. A covariant relativistic approach based on the Vlas…

Thermomagnetic effects on light pseudo-scalar meson masses within the SU(3) Nambu-Jona--Lasinio model

Máximo Coppola, William R. Tavares, Sidney S. Avancini +2

We calculate the screening masses of pseudoscalar mesons in a hot and strongly magnetized medium within the framework of the SU(3) Nambu-Jona--Lasinio model, using a magnetic field…

Collective modes in relativistic cold asymmetric nuclear matter within the covariant Vlasov approach

Aziz Rabhi, Olfa Boukari, Sidney S. Avancini +1

A covariant relativistic approach based on the Vlasov equation is applied to the study of infinite asymmetric nuclear matter. We use several Walecka-type hadronic models and obtain…

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…

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…
