Description
In heavy-ion collisions, strong acceleration can generate an effective temperature via the Unruh effect,$T_U=a/(2\pi)$, which may reach the QCD scale. We study chiral symmetry breaking under acceleration and rotation using effective models. The predicted phase diagram depends on the renormalization scheme: subtracting the Rindler vacuum renders the critical temperature acceleration-independent, while subtracting the Minkowski vacuum enhances the critical temperature. With both acceleration and rotation present, the critical acceleration for chiral restoration decreases with angular velocity. This reveals that acceleration acts like a heat bath and rotation like a chemical potential, cooperatively suppressing the chiral condensate.
