Chiral symmetry breaking in accelerating and rotating frames

We study chiral symmetry breaking and restoration in accelerating and rotating frames using low-energy effective models. By analyzing the chiral condensate in Rindler coordinates, we show that different renormalization schemes lead to distinct conclusions in the accelerating frame: the scheme with subtracting divergences in the Rindler vacuum supports an acceleration-independent critical temperature, while the other scheme with subtracting divergences in Minkowski vacuum suggests an enhanced critical temperature. We further investigate a system with both rotation and acceleration. We find that the critical acceleration for chiral symmetry restoration decreases with angular velocity, indicating cooperative effects from acceleration-induced thermalization and rotation-induced effective chemical potential.
