Topological Charge and the Laminar Structure of the QCD Vacuum

TL;DR

This paper discusses the laminar, sheet-like topological structures in the QCD vacuum revealed by Monte Carlo simulations, and interprets these findings within the theoretical framework of theta-dependence in gauge theories.

Contribution

It provides a detailed analysis of the laminar topological structures in the QCD vacuum and connects simulation results with theoretical understanding of topological effects.

Findings

Revealed laminar, sheet-like topological structures in the QCD vacuum.

Connected Monte Carlo results to theta-dependence in gauge theories.

Demonstrated the coherence and spatial organization of topological charge sheets.

Abstract

Monte Carlo studies of pure glue SU(3) gauge theory using the overlap-based topological charge operator have revealed a laminar structure in the QCD vacuum consisting of extended, thin, coherent, locally 3-dimensional sheets of topological charge embedded in 4D space, with opposite sign sheets interleaved. In this talk I discuss the interpretation of these Monte Carlo results in terms of our current theoretical understanding of theta-dependence and topological structure in asymptotically free gauge theories.
