The most recent publication by Asst. Prof. Gokce Basar and Postdoctoral Associate Xin An, in collaboration with Mikahil Stephanov and Ho-Ung Yee from UIC, appeared today in Physical Review Letters. In this paper, they derive the evolution equations for non-Gaussian measures of thermal fluctuations in hydrodynamics. Fluctuations play a key role in the ongoing search fro the QCD critical point and this work describes how these fluctuations evolve dynamically within the hydrodynamic framework. They also introduce a novel generalization of the Wigner function to higher point correlation functions and develop a diagrammatic technique to organize the expansion in the magnitude of thermal fluctuations.
