Classical universe emerging from quantum cosmology without horizon and flatness problems
M. Fathi, S. Jalalzadeh, Paulo Vargas Moniz
We apply the complex de Broglie–Bohm formulation of quantum mechanics in Chou and Wyatt (Phys Rev A 76: 012115, 2007 ), Gozzi (Phys Lett B 165: 351, 1985 ), Bhalla et al. (Am J Phys 65: 1187, 1997 ) to a spatially closed homogeneous and isotropic early universe whose matter contents are radiation and dust perfect fluids. We then show that an expanding classical universe can emerge from an oscillating (with complex scale factor) quantum universe without singularity. Furthermore, the universe obtained in this process has no horizon or flatness problems.
