Deconfinement phase transition in mirror of symmetries

TL;DR

This paper discusses how the deconfinement phase transition in Yang-Mills theories involves a change from string-like to particle-like degrees of freedom, linked to symmetry transformations, supported by lattice and dual model evidence.

Contribution

It provides a unified perspective on the deconfinement transition as a symmetry-driven change in effective degrees of freedom, extending previous models with new lattice and geometric insights.

Findings

Strings below Tc are replaced by particles above Tc

Deconfinement involves symmetry changes in interactions

Supported by lattice data and dual models

Abstract

We summarize and extend evidence that the deconfinement phase transition in Yang-Mills theories can be viewed as change of effective non-perturbative degrees of freedom and of symmetries of their interactions. In short, the strings in four dimensions (4d) at temperatures below the critical temperature Tc are replaced by particles, or field theories in 3d at T>Tc. The picture emerges within various approaches based, in particular, on dual models, lattice data and field theoretic models. We concentrate mostly on the lattice data, or on the language of quantum geometry.
