SU(2) vacuum dynamics in applied external magnetic field
arXiv:hep-lat/9809042 · doi:10.1016/S0920-5632(99)85161-5
Abstract
The vacuum dynamics of SU(2) lattice gauge theory is studied by means of a gauge-invariant effective action, both at zero and finite temperature. Working with lattices up to 32^4 we check the scaling of the energy density with the magnetic length. We find that the screening at zero temperature of the applied external magnetic field weakens by increasing the temperature.
