Asymptotic Flatness and Quantum Geometry
Sandipan Sengupta
We construct a canonical quantization of the two dimensional theory of a parametrized scalar field on noncompact spatial slices. The kinematics is built upon generalized charge-net…

Quantum geometry with a nondegenerate vacuum: a toy model
Sandipan Sengupta
Motivated by a recent proposal (by Koslowski-Sahlmann) of a kinematical representation in Loop Quantum Gravity (LQG) with a nondegenerate vacuum metric, we construct a polymer quan…

Gravity Asymptotics with Topological Parameters
Sandipan Sengupta
In four dimensional gravity theory, the Barbero-Immirzi parameter has a topological origin, and can be identified as the coefficient multiplying the Nieh-Yan topological density in…
