Spinors in (Anti-)de Sitter Space [PDF]

open access: greenJournal of High Energy Physics, 2023
We explore analytical aspects of correlators involving Dirac spinors in d + 1-dimensional de Sitter space. Adapting the formalism of Sleight and Taronna, we show how to relate processes involving fermions in the in-in formalism to equivalent Witten ...

Superstrings in thermal anti-de Sitter space [PDF]

open access: yesJournal of High Energy Physics, 2021
We revisit the calculation of the thermal free energy for string theory in three-dimensional anti-de Sitter spacetime with Neveu-Schwarz-Neveu-Schwarz flux.

Shift symmetries in (anti) de Sitter space [PDF]

open access: yesJournal of High Energy Physics, 2019
We construct a class of extended shift symmetries for fields of all integer spins in de Sitter (dS) and anti-de Sitter (AdS) space. These generalize the shift symmetry, galileon symmetry, and special galileon symmetry of massless scalars in flat space to

String stars in anti de Sitter space

open access: yesJournal of High Energy Physics, 2022
We study the ‘string star’ saddle, also known as the Horowitz-Polchinski solution, in the middle of d + 1 dimensional thermal AdS space. We show that there’s a regime of temperatures in which the saddle is very similar to the flat space solution found by

Ellis wormholes in anti-de Sitter space [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We construct traversable wormholes with anti-de Sitter asymptotics supported by a phantom field. These wormholes are massless and symmetric with respect to reflection of the radial coordinate $$\eta \rightarrow - \eta $$ η → - η .

Loops in anti de Sitter space

open access: yesJournal of High Energy Physics
We discuss general one and two-loop banana diagrams and one-loop diagrams with external lines with arbitrary masses on the anti de Sitter spacetime by using methods of AdS quantum field theory in the dimensional regularization approach.

Oscillating shells in Anti-de Sitter space [PDF]

open access: greenInternational Journal of Modern Physics D, 2015
We study the dynamics of a spherically symmetric thin shell of perfect fluid embedded in d-dimensional Anti-de Sitter (AdS) spacetime. In global coordinates, besides collapsing solutions, oscillating solutions are found where the shell bounces back and forth between two radii.

Entangling detectors in anti-de Sitter space [PDF]

open access: yesJournal of High Energy Physics, 2019
We examine in (2+1)-dimensional anti-de Sitter (AdS) space the phenomena of entanglement harvesting — the process in which a pair of detectors (two-level atoms) extract entanglement from a quantum field through local interactions with the field. We begin

Higher spin supercurrents in anti-de Sitter space [PDF]

open access: diamondJournal of High Energy Physics, 2018
We propose higher spin supercurrent multiplets for N=1 $$ \mathcal{N}=1 $$ supersymmetric field theories in four-dimensional anti-de Sitter space (AdS).

Twisted string theory in anti-de Sitter space [PDF]

open access: yesJournal of High Energy Physics, 2020
We construct a string theory in three-dimensional anti-de Sitter space-time that is independent of the boundary metric. It is a topologically twisted theory of quantum gravity. We study string theories with an asymptotic N = 2 superconformal symmetry and
