Two lectures on Yang-Lee edge singularity and analytic structure of QCD equation of state
arXiv:2411.02663 · doi:10.21468/SciPostPhysLectNotes.91
Abstract
These lecture notes, prepared for the 2024 XQCD PhD, provide an introduction to the analytic structure of an equation of state near a second-order phase transition and its most prominent landmark: the Yang-Lee edge singularity. In addition to discussing general properties, the notes review recent theoretical progress in locating the QCD critical point by tracking the trajectory of the Yang-Lee edge singularity.
