Algebra of Universal Horizon Preserving Diffeomorphisms
David Mattingly, Matthew Roberson, Sayandeb Basu
In relativistic gravity, requiring a spacetime hypersurface be a Killing horizon breaks the general covariance of general relativity. The residual algebra of horizon preserving dif…
Asymptotically Lifshitz spacetimes with universal horizons in dimensions
Sayandeb Basu, Jishnu Bhattacharyya, David Mattingly +1
Horava gravity theory possesses global Lifshitz space as a solution and has been conjectured to provide a natural framework for Lifshitz holography. We derive the conditions on the…
Asymptotic Safety, Asymptotic Darkness, and the hoop conjecture in the extreme UV
Sayandeb Basu, David Mattingly
Assuming the hoop conjecture in classical general relativity and quantum mechanics, any observer who attempts to perform an experiment in an arbitrarily small region will be stymie…
Constraints from cosmic rays on non-systematic Lorentz violation
Sayandeb Basu, David Mattingly
In this article we analyze the radiation loss from a high energy cosmic ray proton propagating in a spacetime with non-systematic Lorentz violation. From an effective field theory…
Perturbation theory in covariant canonical quantization
Sayandeb Basu
I investigate a new idea of perturbation theory in covariant canonical quantization. I present preliminary results for a toy model of a harmonic oscillator with a quartic perturbat…
Bell's inequality for a single spin 1/2 particle and quantum contextuality
Sayandeb Basu, Somshubhro Bandyopadhyay, Guruprasad Kar +1
We argue that for a \emph{single particle} Bell's inequality is a consequence of noncontextuality and is \emph{incompatible} with statistical predictions of quantum mechanics. Thus…
