The Three - Loop Lattice Free Energy
We calculate the free energy of SU(N) gauge theories on the lattice, to three loops. Our result, combined with Monte Carlo data for the average plaquette, gives a more precise estimate of the gluonic condensate.
متن کاملThree-loop free energy for pure gauge QCD.
We compute the free energy density for pure non-Abelian gauge theory at high temperature and zero chemical potential. The three-loop result to O(g4) is F = dAT 4π 2 9 { − 5 + ( gA 4π )2 − 16 √ 3 ( gA 4π )3 −48 ( gA 4π )4 ln ( gA 2π √ 3 )
متن کاملThe three-loop free energy for high-temperature QED and QCD with fermions
We compute the free energy density for gauge theories, with fermions, at high temperature and zero chemical potential. Specifically, we analytically compute the free energy through O(g4), which requires the evaluation of threeloop diagrams. This computation extends our previous result for pure gauge QCD.
متن کاملFree energy approximations in simple lattice proteins
This work addresses the question of whether it is possible to define simple pairwise interaction terms to approximate free energies of proteins or polymers. Rather than ask how reliable a potential of mean force is, one can ask how reliable it could possibly be. In a two-dimensional, infinite lattice model system one can calculate exact free energies by exhaustive enumeration. A series of appro...
متن کاملPlaquette expectation value and lattice free energy of three - dimensional SU ( N c ) gauge theory
We use high precision lattice simulations to calculate the plaquette expectation value in three-dimensional SU(Nc) gauge theory for Nc = 2, 3, 4, 5, 8. Using these results, we study the Nc-dependence of the first non-perturbative coefficient in the weak-coupling expansion of hot QCD. We demonstrate that, in the limit of large Nc, the functional form of the plaquette expectation value with ultra...
