No FirstOrder Phase Transition in the

"... Within a variational calculation we investigate the role of baryons for the structure of dense matter in the GrossNeveu model. We construct a trial ground state at finite baryon density which breaks translational invariance. Its scalar potential interpolates between widely spaced kinks and antikink ..."

and antikinks at low density and the value zero at infinite density. Its energy is lower than the one of the standard Fermi gas at all densities considered. This suggests that the discrete γ5 symmetry of the GrossNeveu model does not get restored in a first order phase transition at finite density, at variance
THE EXACT RENORMALIZATION GROUP AND FIRSTORDER PHASE TRANSITIONS
, 2000
"... Studies of firstorder 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 firstorder phase transitions for a threedimensional model of two coupled scalar ..."

"... We present the results of a multicanonical simulation of the q=20 2d Potts model in the transition region. This is a very strong first order phase transition. We observe, for the first time, the asymptotic finite size scaling behavior predicted by Borgs and Koteck´y close to a first order phase tra ..."

FIRSTORDER PHASE TRANSITIONS IN AN EARLYUNIVERSE ENVIRONMENT

"... In firstorder phase transitions in the early universe, the bubble wall is expected to be significantly sloweddown by its interaction with the surrounding plasma. We examine the behaviour of the phase of the Higgs field after twobubble collisions, and find that phase differences equilibrate much m ..."

Nucleation of firstorder phase transitions

ON THE STRENGTH OF FIRST ORDER PHASE TRANSITIONS
, 1994
"... Electroweak baryogenesis may solve one of the most fundamental questions we can ask about the universe, that of the origin of matter. It has become clear in the past few years that it also poses a multifaceted challenge. In order to compute the tiny primordial baryonic excess, we probably must invo ..."
Abstract
 Add to MetaCart
by the usual bubble nucleation mechanism, weak transitions are characterized by a mixing of phases as the system reaches the critical temperature from above. I show that it is possible to clearly distinguish between the two, and discuss consequences for studies of first order transitions in general. (Invited
Quantum first order phase transitions

"... The scaling theory of critical phenomena has been successfully extended for classical first order transitions even though the correlation length does not diverge in these transitions. In this paper we apply the scaling ideas to quantum first order transitions. The usefulness of this approach is illu ..."

Cluster Percolation and First Order Phase Transitions
 in the Potts Model”, hepph/0108058; Nucl. Phys. B
"... The qstate Potts model can be formulated in geometric terms, with FortuinKasteleyn (FK) clusters as fundamental objects. If the phase transition of the model is second order, it can be equivalently described as a percolation transition of FK clusters. In this work, we study the percolation structu ..."

In particular, we investigate numerically the percolation behaviour along the line of first order phase transitions of the 3d 3state Potts model in an external field and find that the percolation strength exhibits a discontinuity along
