Holographic entanglement entropy for perturbative higher-curvature gravities
Pablo Bueno, Joan Camps, Alejandro Vilar López
The holographic entanglement entropy functional for higher-curvature gravities involves a weighted sum whose evaluation, beyond quadratic order, requires a complicated theory-depen…
The Parts of the Gravitational Field
Joan Camps
It is argued that, unlike for other fields, the quasilocal parts of the gravitational field are always bounded by surfaces of extremal area.
Superselection Sectors of Gravitational Subregions
Joan Camps
Motivated by the problem of defining the entanglement entropy of the graviton, we study the division of the phase space of general relativity across subregions. Our key requirement…
Exact Gravitational Wave Signatures from Colliding Extreme Black Holes
Joan Camps, Shahar Hadar, Nicholas S. Manton
The low-energy dynamics of any system admitting a continuum of static configurations is approximated by slow motion in moduli (configuration) space. Here, following Ferrell and Ear…
Gravity duals of boundary cones
Joan Camps
The replica trick defines Renyi entropies as partition functions on conically singular geometries. We discuss their gravity duals: regular bulk solutions to the Einstein equations…
Generalized gravitational entropy without replica symmetry
Joan Camps, William R. Kelly
We explore several extensions of the generalized entropy construction of Lewkowycz and Maldacena, including a formulation that does not rely on preserving replica symmetry in the b…
