Polymer Parametrised Field Theory
Alok Laddha, Madhavan Varadarajan
Free scalar field theory on 2 dimensional flat spacetime, cast in diffeomorphism invariant guise by treating the inertial coordinates of the spacetime as dynamical variables, is qu…

A general solution for classical sequential growth dynamics of Causal Sets
Madhavan Varadarajan, David Rideout
A classical precursor to a full quantum dynamics for causal sets has been forumlated in terms of a stochastic sequential growth process in which the elements of the causal set aris…

The graviton vacuum as a distributional state in kinematic Loop Quantum Gravity
Madhavan Varadarajan
The quantum behaviour of weak gravitational fields admits an adequate, albeit approximate, description by those graviton states in which the expectation values and fluctuations of…
