Fermionic determinant for the SU(N) caloron with nontrivial holonomy

چکیده
In the finite-temperature Yang-Mills theory we calculate the functional determinant for fermions in the fundamental representation of SU(N) gauge group in the background of an instanton with non-trivial holonomy at spatial infinity. This object, called the Kraan–van Baal – Lee–Lu caloron, can be viewed as composed of N Bogomolny–Prasad–Sommerfeld monopoles (or dyons). We compute analytically two leading terms of the fermionic determinant at large separations.

Fermionic determinant for dyons and instantons with nontrivial holonomy
We calculate exactly the functional determinant for fermions in fundamental representation of SU(2) in the background of periodic instanton with non-trivial value of the Polyakov line at spatial infinity. The determinant depends on the value of the holonomy v, the temperature, and the parameter r12, which at large values can be treated as separation between the Bogomolny–Prasad– Sommerfeld mono...

We report the observation of calorons with nontrivial holonomy and fractional topological charge objects in cooled lattice samples derived from SU(2) equilibrium ensembles at T < Tc. Characteristic features of QCD are related to the existence of lumps of topological charge in the vacuum. Usually, they are described as instantons or, at T 6= 0, calorons [1] and considered to be the agents of chi...
متن کاملDeterminants in QCD at finite temperature
We compute the functional determinant for the fluctuations around the most general selfdual configuration with unit topological charge for 4D SU(2) Yang-Mills with one compactified direction. This configuration is called “instanton with non-trivial holonomy” or “Kraan-vanBaal-Lee-Lu caloron”. It is a generalization of the usual instantons for the case of non-zero temperature. We extend the earl...
متن کاملCalorons and monopoles from smeared SU ( 2 ) lattice fields at non - zero temperature
In equilibrium, at finite temperature below and above the deconfining phase transition, we have generated lattice SU(2) gauge fields and have exposed them to smearing in order to investigate the emerging clusters of topological charge. Analysing in addition the monopole clusters according to the maximally Abelian gauge, we have been able to characterize part of the topological clusters to corre...

By cooling of equilibrium lattice fields at finite temperature in SU(2) gauge theory it has been shown that topological objects (calorons) observed on the lattice in the confined phase possess a dyonic substructure which becomes visible under certain circumstances. Here we show that, with decreasing temperature of the equilibrium ensemble, the distribution in the caloron parameter space is modi...
