An Effective Model for Glueballs and Dual Superconductivity at Finite Temperature

Penetration depth (a), superconducting , and normal monopole densities with temperature (b). The penetration depth remains constant at representing pure diamagnetic vacuum before it starts rising steadily with and becomes infinite at , where the fields are expected to penetrate the vacuum. Thus, we have a superconducting state at low temperatures, and at relatively high temperatures, we have a mix or intermediate state. On the other hand, the superconducting monopole density decreases with increasing while the normal monopole density increases with an increasing .
