Kerr/CFT Correspondence

- Monica M. Guica, Thomas Hartman, Wei Song, A. Strominger
- Physics, Mathematics
- 25 September 2008

Quantum gravity in the region very near the horizon of an extreme Kerr black hole (whose angular momentum and mass are related by J=GM{sup 2}) is considered. It is shown that consistent boundary… Expand

Three dimensional topologically massive gravity (TMG) with a negative cosmological constant ???2 and positive Newton constant G admits an AdS3 vacuum solution for any value of the graviton mass ?.… Expand

New boundary conditions for AdS3

- G. Compère, Wei Song, A. Strominger
- Physics
- 11 March 2013

A bstractNew chiral boundary conditions are found for quantum gravity with matter on AdS3. The associated asymptotic symmetry group is generated by a single right-moving U(1) Kac-Moody-Virasoro… Expand

Black hole superradiance from Kerr/CFT

- Irene Bredberg, Thomas Hartman, Wei Song, A. Strominger
- Physics
- 21 July 2009

The superradiant scattering of a scalar field with frequency and angular momentum (ω, m) by a near-extreme Kerr black hole with mass and spin (M, J) was derived in the seventies by Starobinsky,… Expand

Chiral gravity, log gravity, and extremal CFT

- A. Maloney, Wei Song, A. Strominger
- Physics
- 26 March 2009

We show that the linearization of all exact solutions of classical chiral gravity around the ${\mathrm{AdS}}_{3}$ vacuum have positive energy. Nonchiral and negative-energy solutions of the… Expand

Holographic derivation of Kerr-Newman scattering amplitudes for general charge and spin

- Thomas Hartman, Wei Song, A. Strominger
- Physics
- 26 August 2009

Near-superradiant scattering of charged scalars and fermions by a near-extreme Kerr-Newman black hole and photons and gravitons by a near-extreme Kerr black hole are computed as certain Fourier… Expand

Entanglement entropy in flat holography

- Hongliang Jiang, Wei Song, Qiang Wen
- Physics
- 22 June 2017

A bstractBMS symmetry, which is the asymptotic symmetry at null infinity of flat spacetime, is an important input for flat holography. In this paper, we give a holographic calculation of entanglement… Expand
