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…
Energy, entropy and the Ricci flow
Joseph Samuel, Sutirtha Roy Chowdhury
The Ricci flow is a heat equation for metrics, which has recently been used to study the topology of closed three manifolds. In this paper we apply Ricci flow techniques to general…
Causal Set Topology
Sumati Surya
The Causal Set Theory (CST) approach to quantum gravity is motivated by the observation that, associated with any causal spacetime (M,g) is a poset (M,<), with the order relation <…
Geometric flows and black hole entropy
Joseph Samuel, Sutirtha Roy Chowdhury
Perelman has given a gradient formulation for the Ricci flow, introducing an ``entropy function'' which increases monotonically along the flow.We pursue a thermodynamic analogy and…
Higher harmonics increase LISA's mass reach for supermassive black holes
K. G. Arun, Bala R. Iyer, B. S. Sathyaprakash +1
Current expectations on the signal to noise ratios and masses of supermassive black holes which the Laser Interferometer Space Antenna (LISA) can observe are based on using in matc…
