Entwinement and the emergence of spacetime
A bstractIt is conventional to study the entanglement between spatial regions of a quantum field theory. However, in some systems entanglement can be dominated by “internal”, possibly gauged, degreesExpand
Bulk curves from boundary data in holography
We embed spherical Rindler space—a geometry with a spherical hole in its center—in asymptotically anti– de Sitter (AdS) spacetime and show that it carries a gravitational entropy proportional to theExpand
Radiation from the non-extremal fuzzball
The fuzzball proposal says that the information of the black hole state is distributed throughout the interior of the horizon in a 'quantum fuzz'. There are special microstates where in the dual CFTExpand
A hole-ographic spacetime
We embed spherical Rindler space – a geometry with a spherical hole in its center – in asymptotically AdS spacetime and show that it carries a gravitational entropy proportional to the area of theExpand
Fractional brane state in the early Universe
In the early Universe matter was crushed to high densities, in a manner similar to that encountered in gravitational collapse to black holes. String theory suggests that the large entropy of blackExpand
Intergalactic magnetic field spectra from diffuse gamma-rays
Non-vanishing parity-odd correlators of gamma ray arrival directions observed by Fermi-LAT indicate the existence of a helical intergalactic magnetic field (Tashiro et al.2013). We successfully testExpand
Emission from the D1D5 CFT: higher twists
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 ofExpand
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 withExpand
Moulting Black Holes
A bstractWe find a family of novel supersymmetric phases of the D1-D5 CFT, which in certain ranges of charges have more entropy than all known ensembles. We also find bulk BPS configurations thatExpand
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 toExpand
