An Effective Model for Glueballs and Dual Superconductivity at Finite Temperature

Figure 6

The screened electric (magnetic) field against . This graph holds for both electric and magnetic fields; thus, both fields are screened from the interior of the vacuum. It was sketched for ; below it, we have a mix or an intermediate state with higher electric or magnetic field strength. Above the estimated , we have a superconducting state because the vacuum is pure diamagnetic with no penetrating electric or magnetic fields.
