Local spinfoam expansion in loop quantum cosmology
Adam Henderson, Carlo Rovelli, Francesca Vidotto +1
The quantum dynamics of the flat Friedmann-Lemaitre-Robertson-Walker and Bianchi I models defined by loop quantum cosmology have recently been translated into a spinfoam-like forma…
Path Integrals and the WKB approximation in Loop Quantum Cosmology
Abhay Ashtekar, Miguel Campiglia, Adam Henderson
We follow the Feynman procedure to obtain a path integral formulation of loop quantum cosmology starting from the Hilbert space framework. Quantum geometry effects modify the weigh…
Vertex Expansion for the Bianchi I model
Miguel Campiglia, Adam Henderson, William Nelson
A perturbative expansion of Loop Quantum Cosmological transitions amplitudes of Bianchi I models is performed. Following the procedure outlined in [1,2] for isotropic models, it is…
Casting Loop Quantum Cosmology in the Spin Foam Paradigm
Abhay Ashtekar, Miguel Campiglia, Adam Henderson
The goal of spin foam models is to provide a viable path integral formulation of quantum gravity. Because of background independence, their underlying framework has certain novel f…
