Galilean Conformal Algebras and AdS/CFT

- A. Bagchi, R. Gopakumar
- Mathematics, Physics
- 9 February 2009

Non-relativistic versions of the AdS/CFT conjecture have recently been investigated in some detail. These have primarily been in the context of the Schrodinger symmetry group. Here we initiate a… Expand

GCA in 2d

- Physics
- 6 December 2009

We make a detailed study of the infinite dimensional Galilean Conformal Algebra (GCA) in the case of two spacetime dimensions. Classically, this algebra is precisely obtained from a contraction of… Expand

Entanglement entropy in Galilean conformal field theories and flat holography.

- PhysicsPhysical review letters
- 15 October 2014

We present the analytical calculation of entanglement entropy for a class of two-dimensional field theories governed by the symmetries of the Galilean conformal algebra, thus providing a rare example… Expand

3D flat holography: entropy and logarithmic corrections

A bstractWe compute the leading corrections to the Bekenstein-Hawking entropy of the Flat Space Cosmological (FSC) solutions in 3D flat spacetimes, which are the flat analogues of the BTZ black holes… Expand

BMS/GCA redux: towards flatspace holography from non-relativistic symmetries

- A. Bagchi, R. Fareghbal
- Mathematics
- 26 March 2012

A bstractThe asymptotic group of symmetries at null infinity of flat spacetimes in three and four dimensions is the infinite dimensional Bondi-Metzner-Sachs (BMS) group. This has recently been shown… Expand

Correspondence between asymptotically flat spacetimes and nonrelativistic conformal field theories.

TLDR

Flat-space chiral gravity.

- A. Bagchi, S. Detournay, D. Grumiller
- PhysicsPhysical review letters
- 8 August 2012

We provide the first evidence for a holographic correspondence between a gravitational theory in flat space and a specific unitary field theory in one dimension lower. The gravitational theory is a… Expand

Tensionless strings and Galilean Conformal Algebra

- A. Bagchi
- Physics, Mathematics
- 1 March 2013

A bstractWe discuss an intriguing link between the symmetries of the tensionless limit of closed string theory and the 2-dimensional Galilean Conformal Algebra (2d GCA). 2d GCA has been studied in… Expand
