Area discreteness, Lorentz covariance and Hilbert space non-separability
Madhavan Varadarajan
We show how quantum discreteness of spatial area is consistent with a unitary implementation of Lorentz boosts in an LQG type quantization of a diffeomorphism invariant reformulati…
Spherical collapse and black hole evaporation
Madhavan Varadarajan
We consider spherically symmetric gravity coupled to a spherically symmetric scalar field with a specific coupling which depends on the Areal Radius. Classical collapse is describe…
Anomaly free quantum dynamics for Euclidean LQG
Madhavan Varadarajan
Classical gravitational evolution admits an elegant and compact re-expression in terms of gauge covariant generalizations of Lie derivatives with respect to a spatial phase space d…
On propagation in Loop Quantum Gravity
Thomas Thiemann, Madhavan Varadarajan
A rigorous implementation of the Wheeler-Dewitt equations was derived in the context of Loop Quantum Gravity (LQG) and was coined Quantum Spin Dynamics (QSD). The Hamiltonian const…
Gravitational dynamics: A novel shift in the Hamiltonian paradigm
Abhay Ashtekar, Madhavan Varadarajan
It is well known that Einstein's equations assume a simple polynomial form in the Hamiltonian framework based on a Yang-Mills phase space. We re-examine the gravitational dynamics…
Euclidean LQG Dynamics: An Electric Shift in Perspective
Madhavan Varadarajan
Loop Quantum Gravity (LQG) is a non-perturbative attempt at quantization of a classical phase space description of gravity in terms of connections and electric fields. As e…
