We study a certain class of nonextremal D1D5 geometries and their ergoregion emission. Using a detailed CFT computation and the formalism developed in [1], we compute the full spectrum and rate of emission from the geometries and find exact agreement with the gravity answer. Previously, only part of the spectrum had been reproduced using a CFT description. We close with a discussion of the context and significance of the calculation.

Quasinormal modes of supersymmetric microstate geometries from the D1-D5 CFT

We revisit the study of the probe scalar quasinormal modes of a class of three- charge super- symmetric microstate geometries. We compute the real and imaginary parts of the quasinormal modes and…

D1-D5-P microstates at the cap

A bstractThe geometries describing D1-D5-P bound states in string theory have three regions: flat asymptotics, an anti-de Sitter throat, and a ‘cap’ region at the bottom of the throat. We identify…

D1-D5-P microstates at the cap

Excitations in the deformed D1D5 CFT

We perform some simple computations for the first order deformation of the D1D5 CFT off its orbifold point. It had been shown earlier that under this deformation the vacuum state changes to a…

Effect of the deformation operator in the D1D5 CFT

A bstractThe D1D5 CFT gives a holographic dual description of a near-extremal black hole in string theory. The interaction in this theory is given by a marginal deformation operator, which is…

Using the D1D5 CFT to Understand Black Holes

In this dissertation, we review work presented in arXiv:0906.2015, arXiv:0907.1663, arXiv:1002.3132, arXiv:1003.2746, and arXiv:1007.2202 on the D1D5 system. We begin with some motivational material…

Lifting of D1-D5-P states

A bstractWe consider states of the D1-D5 CFT where only the left-moving sector is excited. As we deform away from the orbifold point, some of these states will remain BPS while others can ‘lift’. We…

String dynamics in NS5-F1-P geometries

A bstractString theory dynamics on certain fivebrane supertube backgrounds is described by an exactly solvable null-gauged WZW model. We use this description to compute the spectrum of closed string…

Black hole microstates from the worldsheet

Recently an exact worldsheet description of strings propagating in certain black hole microstate geometries was constructed in terms of null-gauged WZW models. In this paper we consider a family of…

Deforming the D1D5 CFT away from the orbifold point

The D1D5 brane bound state is believed to have an ‘orbifold point’ in its moduli space which is the analogue of the free Yang Mills theory for the D3 brane bound state. The supergravity geometry…

Emission from the D1D5 CFT

It is believed that the D1D5 brane system is described by an `orbifold CFT' at a special point in moduli space. We first develop a general formulation relating amplitudes in a d-dimensional CFT to…

Instability of nonsupersymmetric smooth geometries

Recently certain nonsupersymmetric solutions of type IIb supergravity were constructed [V. Jejjala, O. Madden, S. F. Ross, and G. Titchener, Phys. Rev. D 71, 124030 (2005).], which are everywhere…

The D1/D5 System And Singular CFT

We study the conformal field theory of the D1/D5 system compactified on X (X is T4 or K3). It is described by a sigma model whose target space is the moduli space of instantons on X. For values of…

Non-extremal fuzzballs and ergoregion emission

In the traditional picture of black holes, Hawking radiation is created by pair creation from the vacuum at the horizon. In the fuzzball proposal, individual microstates do not have a horizon with…

Holographic anatomy of fuzzballs

We present a comprehensive analysis of 2-charge fuzzball solutions, that is, horizon-free non-singular solutions of IIB supergravity characterized by a curve on R4. We propose a precise map that…

Adding momentum to D1-D5 system

We construct the first example of asymptotically flat solution which carries three charges (D1, D5 and momentum) and which is completely regular everywhere. The construction utilizes the relation…

Pair creation in non-extremal fuzzball geometries

It is possible to construct a special family of non-extremal black hole microstates. These microstates are unstable, and emit radiation at a rate which is found to exactly equal the Hawking radiation…
