Numerical corrections to the strong coupling effective Polyakov-line action for finite T Yang-Mills theory
Georg Bergner, Jens Langelage, Owe Philipsen
We consider a three-dimensional effective theory of Polyakov lines derived previously from lattice Yang-Mills theory and QCD by means of a resummed strong coupling expansion. The e…

Lattice QCD at finite density suffers from a severe sign problem, which has so far prohibited simulations of the cold and dense regime. Here we study the onset of nuclear matter em…
