Vortex liquid in the superconducting vacuum of the quenched QCD induced by strong magnetic field

Abstract : In the background of the strong magnetic field the vacuum is suggested to possess an electromag- netically superconducting phase characterised by the charged ρ-meson condensate. The ρ-meson condensate is inhomogeneous due to the presence of the string-like defects which are parallel to the magnetic field. In agreement with these expectations, we have observed the presence of the ρ-vortices in numerical simulations of the vacuum of the quenched two-color lattice QCD in strong magnetic field background. We have found that in the quenched QCD the ρ-vortices form a liquid.
