Fig. 2: Cooper pairs–quantum magnetic monopoles phase diagram at T = 0.

The parameter \(\eta =2\pi (mv\ell )G/\sqrt{{\mu }_{{\rm{N}}}{\mu }_{{\rm{A}}}}\) encodes the strength of quantum fluctuations and the material properties of the system. The inter-phases lines are η = 1/γ(γ < 1, η > 1), γ = 1 (η < 1), and η = γ (η > 1, γ > 1).
