Causal loop quantum gravity and cosmological solutions
Department of Physics, University of Tehran - Tehran, Iran
Accepted: 21 July 2005
We shall present here the causal interpretation of canonical quantum gravity in terms of new variables. Then we shall apply it to the minisuperspace of cosmology. A vacuum solution of quantum cosmology is obtained and the Bohmian trajectory is investigated. At the end a coherent state with matter is considered in the cosmological model.
