Tytuł:: Three dimensional finite temperature SU(3) gauge theory near the phase transition

Opis:: We have measured the correlation function of Polyakov loops on the lattice in three dimensional gauge theory near its finite temperature phase transition. Using a new and powerful application of finite size scaling, we furthermore extend the measurements of the critical couplings to considerably larger values of the lattice sizes, both in the temperature and space directions, than was investigated earlier in this theory. With the help of these measurements we perform a detailed finite size scaling analysis, showing that for the critical exponents of the two dimensional three state Potts model the mass and the susceptibility fall on unique scaling curves. This strongly supports the expectation that the gauge theory is in the same universality class. The Nambu–Goto string model on the other hand predicts that the exponent ν has the mean field value, which is quite different from the value in the abovementioned Potts model. Using our values of the critical couplings we also determine the continuum limit of the value of the critical temperature in terms of the square root of the zero temperature string tension. This value is very near to the prediction of the Nambu–Goto string model in spite of the different critical behaviour.

Tytuł:: Focusing on the fixed point of 4D simplicial gravity
Autorzy:: Krzywicki, A.

Burda, Zdzisław
Opis:: Our earlier renormalization group analysis of simplicial gravity is extended. A high-statistics study of the volume and coupling constant dependence of the cumulants of the node distribution is carried out. It appears that the phase transition of the theory is of first order, contrary to what is generally believed.
