Abstract

The interactions of anyonic quasiparticles (vortices) in a Chern-Simons-Landau-Ginzburg theory of the fractional quantum Hall effect is investigated and we show that it manifestly realizes a hybridization of type I or II superconductivity. Through Gauss’s law, each vortex simultaneously carries a flux quantum and a proportional Noether charge, thereby realizing an anyonic excitation. The Chern-Simons coupling modifies the screening structure of the gauge fields, producing complex-conjugate masses that yield a common magnetic and electric penetration depth with an oscillatory phase. This altered asymptotic behavior breaks the conventional type-I and type-II dichotomy of the Ginzburg-Landau model, thereby enhancing the superconducting typology within a single-component condensate. As a result, vortex anyons experience short-range repulsion and long-range attraction, enabling the formation of separated multivortex bound states with nonmonotonic interaction energy. This provides a minimal topological route to hybrid superconductivity without multicomponent order parameters or nonlocal interactions.
