We review the current status of the research on effective nonlocal NJL-like chiral quark models with separable interactions, focusing on the application of this approach to the description of the properties of hadronic and quark matter under extreme conditions. The analysis includes the predictions for various hadron properties in vacuum, as well as the study of the features of deconfinement and chiral restoration phase transitions for systems at finite temperature and/or density. We also address other related subjects, such as the study of phase transitions for imaginary chemical potentials, the possible existence of inhomogeneous phase regions, the presence of color superconductivity, the effects produced by strong external magnetic fields, and the application to the description of compact stellar objects.

Lee--Yang edge singularities in Nonlocal Nambu--Jona-Lasinio Model
hep-ph 2025-09 conditional novelty 6.0 of 10

In a nonlocal NJL model, Lee-Yang edge singularities follow trajectories that end at the QCD critical point, with critical exponent 1.494(1) matching mean-field scaling.
