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…

On the origin of the peak of the sound velocity for isospin imbalanced strongly interacting matter
Alejandro Ayala, Bruno S. Lopes, Ricardo L. S. Farias +1
We study the properties of a system composed of strongly interacting matter with an isospin imbalance, using as an effective description of QCD the two-flavor Linear Sigma Model wi…

Describing the speed of sound peak of isospin-asymmetric cold strongly interacting matter using effective models
Alejandro Ayala, Bruno S. Lopes, Ricardo L. S. Farias +1
The non-monotonic behavior of the speed of sound for isospin imbalanced strongly interacting matter, found by recent lattice QCD simulations, can be reproduced within the Nambu--Jo…
