Neutron stars: new constraints on asymmetric dark matter
O. Ivanytskyi, V. Sagun, I. Lopes
We study an impact of asymmetric dark matter on properties of the neutron stars and their ability to reach the two solar masses limit, which allows us to present a new range of mas…

Second look to the Polyakov Loop Nambu-Jona-Lasinio model at finite baryonic density
O. Ivanytskyi, M. Ángeles Pérez-García, V. Sagun +1
We revisit the Polyakov Loop coupled Nambu-Jona-Lasinio model that maintains the Polyakov loop dynamics in the limit of zero temperature. This is of interest for astrophysical appl…

Tetraneutron condensation in neutron rich matter
O. Ivanytskyi, M. Ángeles Pérez-García, C. Albertus
In this work we investigate the possible condensation of tetraneutron resonant states in the lower density neutron rich gas regions inside Neutron Stars (NSs). Using a relativistic…
