Loop Quantum Gravity on Non-Compact Spaces
Matthias Arnsdorf, Sameer Gupta
We present a general procedure for constructing new Hilbert spaces for loop quantum gravity on non-compact spatial manifolds. Given any fixed background state representing a non-co…

Causality in Spin Foam Models
Sameer Gupta
We compute Teitelboim's causal propagator in the context of canonical loop quantum gravity. For the Lorentzian signature, we find that the resultant power series can be expressed a…

Propagating spin modes in canonical quantum gravity
Roumen Borissov, Sameer Gupta
One of the main results in canonical quantum gravity is the introduction of spin network states as a basis on the space of kinematical states. To arrive at the physical state space…
