TY - JOUR ID - 406811 AU - Bojowald, Martin - Hinterleitner, Franz PY - 2002 TI - Isotropic loop quantum cosmology with matter JF - Physical Revue D VL - 2002 IS - 66 SP - 104003 EP - 104003 PB - The American Physical Society SN - 05562821 KW - Loop quantum cosmology KW - Euclidean Hamiltonian KW - discrete time evolution N2 - The isotropic, spatially flat Friedmann model is coupled to a massless scalar field. The hailtonian constraint equation is solved exactly in the framework of loop quantum gravity. Time evolution is constructed with respect to the radius of the universe as an internal time. Due to the discrete nature of geometry in the loop formalism this time evolution becomes discrete, too. It displays the correct classical limit but avoids the singularity of the classical counterpart. ER -
