FINITE-SIZE VERSUS FINITE-TEMPERATURE EFFECTS IN THE CRITICAL LONG-RANGE O(N) MODEL

Abstract In this paper we consider classical and quantum versions of the critical long-range O(N) model, for which we study finite-size and finite-temperature effects, respectively, at large N.First, we consider the classical (isotropic) model, which is conformally invariant at criticality, and we introduce one compact spatial direction.We show tha

The spread of economic shocks in an increasingly interconnected global economy has been subject to several studies recently.These studies mostly focus on the synchronization of business cycles among economies and search for the relationship between trade linkages and shock contagion.In contrast to previous studies in the field, this paper focuses o
