A nested sequence of inequivalent Rindler vacua : Universal Relic Thermality of Planckian origin
Kinjalk Lochan, T. Padmanabhan
The Bogoliubov transformation connecting the standard inertial frame mode functions to the standard mode functions defined in the Rindler frame , leads to the result that the…
Geodesic distance: A descriptor of geometry and correlator of pre-geometric density of spacetime events
T. Padmanabhan
Classical geometry can be described either in terms of a metric tensor or in terms of the geodesic distance . Recent work, however, has shown that the geodes…
Exploring the Rindler vacuum and the Euclidean Plane
Karthik Rajeev, T. Padmanabhan
In flat spacetime, two inequivalent vacuum states which arise rather naturally are the Rindler vacuum (R) and the Minkowski vacuum (M). We disuss several aspects of the Rindler vac…
The Kinetic Theory of the Mesoscopic Spacetime
T. Padmanabhan
At the mesoscopic scales --- which interpolate between the macroscopic, classical, geometry and the microscopic, quantum, structure of spacetime --- one can identify the density of…
Entropy of a generic null surface from its associated Virasoro algebra
Sumanta Chakraborty, Sourav Bhattacharya, T. Padmanabhan
Null surfaces act as one-way membranes, blocking information from those observers who do not cross them (e.g., in the black hole and the Rindler spacetimes) and these observers ass…
The Atoms Of Space, Gravity and the Cosmological Constant
T. Padmanabhan
I describe an approach which connects classical gravity with the quantum microstructure of spacetime. The field equations arise from maximizing the density of states of matter plus…
