Rotation effect on the thermodynamics of QCD matter*
Abstract In this study, we investigated the impact of rotation on the thermodynamic properties of QCD matter using the three-flavor NJL model. We examined the dependencies of key thermodynamic quantities, such as the trace anomaly, specific heat, speed of sound, angular momentum, and moment of inertia, on temperature, quark chemical potential, and angular velocity. Our main finding is that the speed of sound exhibits a nonmonotonic behavior as the angular velocity varies.
