Noncommutative Quantum Cosmology

H. García-Compeán, O. Obregón, and C. Ramírez

Abstract

We propose a model for noncommutative quantum cosmology by means of a deformation of minisuperspace. For the Kantowski-Sachs metric we are able to find the exact wave function. We construct wave packets and show that new quantum states that “compete” to be the most probable state appear, in clear contrast with the commutative case. A tunneling process could be possible among these states.
