Renormalization-Group Study of Weakly First-Order Phase Transitions
We study the universal critical behavior near weakly first-order phase transitions for a three-dimensional model of two coupled scalar fields – the cubic anisotropy model. Renormalization-group techniques are employed within the formalism of the effective average action. We calculate the coarse-grained free energy and deduce the universal ratio of susceptibilities on either side of the phase tr...
متن کاملThe Exact Renormalization Group and First-order Phase Transitions
Studies of first-order phase transitions through the use of the exact renormalization group are reviewed. In the first part the emphasis is on universal aspects: We discuss the universal critical behaviour near weakly first-order phase transitions for a three-dimensional model of two coupled scalar fields – the cubic anisotropy model. In the second part we review the application of the exact re...
متن کاملExact renormalization-group analysis of first-order phase transitions in clock models.
We analyze the exact behavior of the renormalization group flow in one-dimensional clock-models which undergo first order phase transitions by the presence of complex interactions. The flow, defined by decimation, is shown to be single-valued and continuous throughout its domain of definition, which contains the transition points. This fact is in disagreement with a recently proposed scenario f...
متن کاملRadiatively-Induced First-Order Phase Transitions: The Necessity of the Renormalization Group
We advocate a (Wilson) renormalization-group (RG) treatment of finitetemperature first-order phase transitions, in particular those driven by radiative corrections such as occur in the standard model, and other spontaneously-broken gauge theories. We introduce the scale-dependent coarse-grained free energy SΛ[φ] which we explicitly calculate, using the Wilson RG and a (4 − ε)-expansion, for a s...
متن کاملEnvironmentally Friendly Renormalization Group and Phase Transitions
We discuss an environmentally friendly renormalization group approach to analyze phase transitions. We intend to apply this method to the Electroweak Phase Transition. This work is in progress. We present some previously obtained results concerning a λφ 4 theory, where the main features of this algorithm are introduced.
