At the temperature of the order of 10 -5 K, the energy density of its state corresponds to the dark energy density in absolute magnitude. The cosmological constant for such material medium turns out to be negative. %K Dark Energy %K Cosmological Constant %K Stochastic Electromagnetic Field %K Spinor Particles %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=67740
