Spontaneous creation of chromomagnetic field and A_0-condensate at high temperature on a lattice
Abstract
Description
In a lattice formulation of SU(2)-gluodynamics, the spontaneous generation of chromomagnetic fields at high temperature is investigated. A procedure to determine this phenomenon is developed. By means of the $χ^2$-analysis of the data set accumulating $5-10\times 10^6$ Monte Carlo configurations, the spontaneous creation of the Abelian color magnetic field is indicated. The common generation of the magnetic field and $A_0$-condensate is also studied. It is discovered that the field configuration consisting of the magnetized vacuum and the $A_0$-condensate is stable.
