Abstract
In this work, we apply a previous proposal to study noncommutative cosmology and apply it to inflation, we analyze an FRW cosmological background with a scalar field, via the WDW equation. In this scenario noconmmutativity is introduced in the gravitational field as well as in the scalar field through a deformation of minisuperspace and are able to find an exact the noncommutative wave function.
Keywords: Quantum cosmology; noncommutative quantum mechanics.
Resumen
En este trabajo aplicamos propuestas previas al estudio de la cosmología no conmutativa aplicando esto a inflación, analizamos un modelo cosmológico FRW con un campo escalar a través de la ecuación WDW. En este escenario la no conmutatividad es introducida entre el campo gravitacional y el campo escalar por medio de la deformación de las relaciones de conmutación en el minisuperespacio y nos es posible encontrar soluciones exactas para la función de onda.
Descriptores: Cosmología cuantica; mecánica cuántica noconmutativa.
