Effective Potential for Polyakov Loops in Lattice QCD
Precise measurement of Polyakov loop correlation is important for finite temperature physics. First of all heavy quark potentials at finite temperature are obtained by measuring twoPolyakov-loop correlation functions. It is already well-known that we can obtain the QQ̄ potential below and above the critical temperature (TC) from this measurement. Due to the nonperturbative effects, however, ther...

Using a variant of the IMCRG method of Gupta and Cordery, we explicitly compute majority rule block spin effective actions for the signs of the Polyakov loops in 4D SU(2) finite temperature lattice gauge theories. To the best of our knowledge, this is the first attempt to compute numerically effective actions for the Polyakov loop degrees of freedom in 4D SU(2). The most important observations ...
متن کاملConnecting Polyakov Loops to Hadrons
Importance sampling lattice simulations are able to provide vital information about the nature of the temperature driven phase transition for 2 and 3 color Yang-Mills theories with and without matter fields (see [ 5, 6] for 3 colors). At zero temperature the SU(N) Yang-Mills theory is asymptotically free, and the physical spectrum of the theory consists of a tower of hadronic states referred to...
متن کاملOn 4D-Hawing Radiation from Effective Action
We determine the s-waves contribution of a scalar field to the four dimensional effective action for arbitrary spherically symmetric external gravitational fields. The result is applied to 4d-black holes and it is shown that the energy momentum tensor derived from the (nonlocal) effective action contains the Hawking radiation. The luminosity is close to the expected one in the s-channel. The en...
متن کاملPolyakov Loops in 2 D QCD
We discuss SU(N) gluo-dynamics at finite temperature and on a spatial circle. We show that the effective action for the Polyakov Loop operator is a one dimensional gauged SU(N) principle chiral model with variables in the loop space and loop algebra of the gauge group. We find that the quantum states can be characterized by a discrete θ-angle which appears with a particular 1-dimensional topolo...
