Instanton interactions in dense-matter QCD
arXiv:hep-ph/0103099 · doi:10.1016/S0370-2693(01)00607-4
Abstract
A Coulomb gas representation of dense-matter QCD is derived from a dual transformation of the low-energy effective Lagrangian. The point-like charges Q=+1,-1 of the gas are identified with the instantons and anti-instantons of such topological charges. An instanton repels another instanton with the same force as it attracts an anti-instanton, in contrast to the semiclassical interaction.
