It is shown that the Schottky-barrier-induced electric field which is confined in the depletion region ... More

Yang-Mills condensate dark energy coupled with matter and radiationSep 26 2006The coincidence problem is studied for the dark energy model of effective Yang-Mills condensate in a flat expanding universe during the matter-dominated stage. The YMC energy $\rho_y(t)$ is taken to represent the dark energy, which is coupled either with ... More
