Asymptotically anti-de Sitter spacetimes: conserved quantities
- A. Ashtekar, Saurya Das
- Mathematics
- 29 November 1999
Asymptotically anti-de Sitter spacetimes are considered in a general dimension d 4. As one might expect, the boundary conditions at infinity ensure that the asymptotic symmetry group is the anti-de…
Universality of quantum gravity corrections.
- Saurya Das, E. Vagenas
- PhysicsPhysical review letters
- 29 October 2008
We show that the existence of a minimum measurable length and the related generalized uncertainty principle (GUP), predicted by theories of quantum gravity, influence all quantum Hamiltonians. Thus,…
A proposal for testing quantum gravity in the lab
- A. Ali, Saurya Das, E. Vagenas
- Physics
- 15 July 2011
Attempts to formulate a quantum theory of gravitation are collectively known as quantum gravity. Various approaches to quantum gravity such as string theory and loop quantum gravity, as well as black…

General logarithmic corrections to black-hole entropy
- Saurya Das, P. Majumdar, R. K. Bhaduri
- Physics
- 31 October 2001
We compute leading-order corrections to the entropy of any thermodynamic system due to small statistical fluctuations around equilibrium. When applied to black holes, these corrections are shown to…
Discreteness of space from GUP II: Relativistic wave equations

Phenomenological implications of the generalized uncertainty principle
- Saurya Das, E. Vagenas
- Physics
- 13 January 2009
Various theories of quantum gravity argue that near the Planck scale, the Heisenberg uncertainty principle should be replaced by the so called generalized uncertainty principle (GUP). We show that ...
Will we observe black holes at LHC
- M. Cavaglià, Saurya Das, Roy Maartens Portsmouth, N. Brunswick
- Physics
- 20 May 2003
The generalized uncertainty principle, motivated by string theory and non-commutative quantum mechanics, suggests significant modifications to the Hawking temperature and evaporation process of black…
Conserved quantities in Kerr-anti-de Sitter spacetimes in various dimensions
- Saurya Das, R. Mann
- Physics
- 1 August 2000
We compute the conserved charges for Kerr anti-de Sitter spacetimes in various dimensions using the conformal and the counterterm prescriptions. We show that the conserved charge corresponding to the…
Energy and efficiency of adiabatic quantum search algorithms

- Physics
- 9 April 2002
We present the results of a detailed analysis o fag eneral, unstructured adiabatic quantum search of a database of N items. In particular, we examine the effects on the computation time of adding…
