We find the critical behavior of ¿tq¿, as a function of q, for free processes. We also show that the addition of a potential can destroy criticality.5 p.application/pdfeng(c) The American Physical Society, 1990Distribució (Teoria de la probabilitat)Fluctuacions (Física)Processos estocàsticsProbability theoryFluctuations (Physics)Stochastic processesinfo:eu-repo/semantics/article53706info:eu-repo/semantics/openAccess
