A Hamiltonian Formulation of the BKL Conjecture
Abhay Ashtekar, Adam Henderson, David Sloan
The Belinskii, Khalatnikov and Lifshitz conjecture \cite{bkl1} posits that on approach to a space-like singularity in general relativity the dynamics are well approximated by `igno…
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…
