The Cosmological Constant and the Deconstruction of Gravity
Vishnu Jejjala, Robert G. Leigh, Djordje Minic
Witten has presented an argument for the vanishing of the cosmological constant in 2+1 dimensions. This argument is crucially tied to the specific properties of (2+1)-dimensional g…
Non-commutative Chern-Simons for the Quantum Hall System and Duality
Eduardo Fradkin, Vishnu Jejjala, Robert G. Leigh
The quantum Hall system is known to have two mutually dual Chern-Simons descriptions, one associated with the hydrodynamics of the electron fluid, and another associated with the s…
PP-Waves and Holography
Robert G. Leigh, Kazumi Okuyama, Moshe Rozali
We consider aspects of holography in the -wave limit of . This geometry contains two $\RR4$'s, one obtained from directions, and the other from the $S 5…
De Sitter Holography and the Cosmic Microwave Background
Finn Larsen, Jan Pieter van der Schaar, Robert G. Leigh
We interpret cosmological evolution holographically as a renormalisation group flow in a dual Euclidean field theory, as suggested by the conjectured dS/CFT correspondence. Inflati…
