2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/50203We discuss the relevance of the Lee-Yang edge singularity to the finite-temperature Z_2-symmetry restoration transition of the Gross-Neveu model in three dimensions. We present an explicit result for its large-N free energy density in terms of Zeta(3) and the absolute maximum of Clausen's function.8 pages, LaTexHigh Energy Physics - TheoryStatistical MechanicsHigh Energy Physics - Latticetext
