We investigate the possible existence of anomalous mass defects in the low mass region of stellar sequences of strange stars. We employ the nonperturbative equation of state derived in the framework of the Field Correlator Method to describe the hydr

In this Letter, we investigate nonextensive effects on phase transition in nuclear matter in the context Walecka many-body field theory. A difference is observed when the results calculated for the nuclear matter at vanishing baryon density is compar

We investigate possible effects of quantum power-law statistical mechanics on the relativistic nuclear equation of state in the context of the Walecka quantum hadrodynamics theory. By considering the Kaniadakis non-Gaussian statistics, characterized

Self-similar solutions of a collapsing perfect fluid and a massless scalar field with kinematic self-similarity of the first kind in 2+1 dimensions are obtained. Their local and global properties of the solutions are studied. It is found that some of

By using a $q$-calculus, the Walecka many-body field theory was studied in the context of the Tsallis framework. The most important aspect of the application of the $q$-calculus to the nonadditive formulation of QHD-I is that it naturally emerges as

The Walecka many-body field theory is investigated in the context of quantum nonextensive statistical mechanics, characterized by a dimensionless parameter $q$. We consider nuclear matter described statistically by a power-law distribution which gene
