Talk Title |
Quantum corrections in quantum spacetime |
|
Abstract |
I consider a theory of two scalar fields on a flat Friedmann-Robertson-Walker spacetime. I introduce fluctuations of the fields and of metric tensor. Then I quantise both fluctuations and background fields using perturbation theory. Background fields are quantised in Loop Quantum Cosmology manner with one of fields giving "relational time" and the other one set as test field." |
