Description
In this talk, I will give an overview of the universal critical dynamics at the chiral phase transition of two-flavor QCD in the chiral limit. I will review the general argument about the dynamic universality class by explicitly constructing the stochastic equations of motion in the vicinity of the second-order phase transition. To extract dynamic universal quantities associated with these stochastic equations, we use a novel formulation of the functional renormalization group for dynamical systems with "reversible mode couplings". I will show results for dynamic universal quantities like the non-trivial value $z=d/2$ of the dynamic critical exponent at the strong-scaling fixed point (where $d$ is the number of spatial dimensions) and the dynamic universal scaling function for the isovector and isoaxial-vector charge diffusion coefficient. Beyond universality, I will show preliminary results about the size of the dynamic scaling region along the temperature axis.
