DESCRIPTION:Speakers: Bardiya Bahrampour (Justus-Liebig University Giessen
)\nThe strong coupling expansion of the lattice gauge action leads to a Po
lyakov loop model that effectively describes the gluodynamic at low temper
atures and together with the hopping expansion of\nthe fermion determinant
allows for insights into the QCD phase diagram at finite density and low
temperatures\, although the accessible pion masses are rather large.\nAt h
igh temperatures the strong coupling expansion breaks down and it is expec
ted that the interaction of Polyakov loops becomes non-local.\nTherefore w
e use inverse Monte-Carlo methods to map pure SU(2) gluodynamic to differe
nt non-local Polyakov models . We take into account Polyakov loops in high
er representations and gradually add interaction terms at larger distances
to investigate how well we can describe the full theory. Particularly we
are interested in the behaviour of those models when extrapolating the de
pendency of non-local terms and higher represenations\, especially in the
large volume limit. We try to find connections between the strength of the
coupling of the non-local terms (with respect to the interaction distanc
e) and the correlation length of the full theory at a given value of the g
auge coupling in order to compare our results to existing proposals for no
n-local effective actions.\n\nhttps://conference.ippp.dur.ac.uk/event/470/
