Abstract We study finite volume effects within the Polyakov loop Nambu-Jona-Lasinio model for two light and one heavy quarks at vanishing baryon chemical potential and finite temperatures. We include three different Polyakov loop potentials and ensur

We study cold strange quark stars employing an enhanced version of the quark-mass density-dependent model, which incorporates excluded volume effects to address non-perturbative QCD repulsive interactions. We provide a comparative analysis of our mas

We study the phase diagram in the $T-\mu$ plane for quark matter under the influence of a strong uniform magnetic field $\vec{B}$, in the framework of a non-local extension of the two-flavor Polyakov Nambu-Jona-Lasinio model. We analyze the deconfine

We revisit the quark-mass density-dependent model -- a phenomenological equation of state for deconfined quark matter in the high-density low-temperature regime -- and show that thermodynamic inconsistencies that have plagued the model for decades, c

An effective Lagrangian for quark pairing in nonlinear chromodielectric models (CDM) is derived in the leading order. The effective pairing coupling depends explicitly on the confinement field, χ, of the CDM manifesting a confinement effect on color

We derive an effective Lagrangian for pairing in nonlinear chromodielectric models (CDM), in leading order. The effective pairing coupling depends explicitly on the confinement field, χ , of the CDM. The self-consistent gap equations are constructed

In the present work we study a relativistic quark model at finite temperature and density with non‐local quark‐antiquark and quark‐quark interactions with SU(2) flavour and SU(3) color symmetries. After proper bosonization, we analyze the struc
