Is there a third - order phase transition in quenched QCD ?
We discuss the connection between the contributions of large field configurations and the large order behavior of perturbation theory. For quenched QCD, the sensitivity of the average plaquette to a removal of large field configurations has a narrow peak near β = 5.6. Various analysis of the order 10 weak coupling series for the plaquette give robust indications for a singularity in the third d...
متن کاملEFFECT OF THE NEXT-NEAREST NEIGHBOR INTERACTION ON THE ORDER-DISORDER PHASE TRANSITION
In this work, one and two-dimensional lattices are studied theoretically by a statistical mechanical approach. The nearest and next-nearest neighbor interactions are both taken into account, and the approximate thermodynamic properties of the lattices are calculated. The results of our calculations show that: (1) even though the next-nearest neighbor interaction may have an insignificant ef...
متن کاملThermodynamic Properties of the Discommensuration Point for Incommensurate Structures: a ”third-order” Phase Transition
It is well known that the modulation function of an incommensurate modulated phase is smooth at the transition from disordered to incommensurate, and that it may become discontinuous further from the transition line. In the incommensurate phase it marks the transition from a simple modulation to a structure that is locally like the commensurate structure that usually appears at another phase tr...
متن کاملOn the existence of a third-order phase transition beyond the Andrews critical point: a molecular dynamics study.
The possibility of the existence of a gas-liquid third order phase transition for fluids is becoming a subject of growing interest. Experimental work suggests its existence for specific systems while recent theoretical models claim its universality. In this work, we employ Molecular Dynamics and investigate the third-order phase transition beyond the Andrews critical point by treating a system ...
متن کاملOrder of superconductive phase transition
On the occasion of Reinhard Folk's 60th birthday, I give a brief review of the theoretical progress in understanding the critical properties of super-conductors. I point out the theoretical difficulties in finding a second-order transition in the Ginzburg-Landau Model with O(N)-symmetry in 4 − ε Dimensions , and the success in predicting the existence and location of a tricritical point with th...
