Dyon Condensation and Dual Superconductivity in Quantum Chromodynamics: An Abelian Higgs Model Approach

Abstract

This study investigates dyon condensation and the emergence of dual superconductivity within the Abelian Higgs framework of Quantum Chromodynamics (QCD). By analyzing these non-perturbative mechanisms, the work offers deeper insight into the complex behavior of QCD under extreme conditions, such as high temperature and high baryon density. Dyons particles carrying both electric and magnetic charges exhibit a distinctive response in which they screen the gauge potentials to which they are directly coupled, while simultaneously inducing antiscreening effects in the corresponding dual potentials. This interplay is consistent with a generalized Meissner effect and leads naturally to the realization of dual superconductivity. The effective action for dyonic fields, obtained through the Abelian projection of QCD, explicitly demonstrates this mechanism and reinforces the confinement scenario via the behavior of the Wilson loop within the Abelian Higgs model. This formulation provides a coherent theoretical description of confinement and phase transitions in strongly interacting matter. The results presented here deepen our understanding of the QCD vacuum structure and have important implications for both theoretical and experimental physics, with relevance extending from particle physics to cosmology. Ultimately, this study contributes to a more unified and comprehensive picture of the fundamental interactions governing matter in the universe.
