Quantum extremal islands made easy. Part II. Black holes on the brane [PDF]
Journal of High Energy Physics, 2020 We discuss holographic models of extremal and non-extremal black holes in contact with a bath in d dimensions, based on a brane world model introduced in [1].

Quantum extremal islands made easy. Part I. Entanglement on the brane [PDF]
Journal of High Energy Physics, 2020 Recent progress in our understanding of the black hole information paradox has lead to a new prescription for calculating entanglement entropies, which involves special subsystems in regions where gravity is dynamical, called quantum extremal islands. We

Effect of the Brane-Dicke coupling parameter on weak gravitational lensing by wormholes and naked singularities [PDF]
Physical Review D, 2019 In this paper, we analyze the deflection angle of light by Brane-Dicke wormhole in the weak field limit approximation to find the effect of the Brane-Dicke coupling parameter on the weak gravitation lensing.

Living Reviews in Relativity, 2004 The observable universe could be a 1+3-surface (the “brane”) embedded in a 1+3+d-dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk.

M5-brane and D-brane scattering amplitudes [PDF]
Journal of High Energy Physics, 2017 We present tree-level n-particle on-shell scattering amplitudes of various brane theories with 16 conserved supercharges. These include the world-volume theory of a probe D3-brane or D5-brane in 10D Minkowski spacetime as well as a probe M5-brane in 11D ...

Emergence of spontaneously broken supersymmetry on an anti-D3-brane in KKLT dS vacua [PDF]
Journal of High Energy Physics, 2014 A bstractThe KKLT construction of de Sitter vacua includes an uplifting term coming from an anti-D3-brane. Here we show how this term can arise via spontaneous breaking of supersymmetry, based on the emergence of a nilpotent chiral supermultiplet on the ...

Quantum extremal islands made easy. Part III. Complexity on the brane [PDF]
Journal of High Energy Physics, 2020 We examine holographic complexity in the doubly holographic model introduced in [1, 2] to study quantum extremal islands. We focus on the holographic complexity=volume (CV) proposal for boundary subregions in the island phase.

Constraining the tidal charge of brane black holes using their shadows [PDF]
The European Physical Journal C, 2020 A constraint on the tidal charge generated within a brane world is shown. Using the shadow of a rotating black hole in a brane context in order to describe the M87* parameters recently announced by the Event Horizon Telescope Collaboration, the deviation

Universe, 2022 We introduce QP manifolds that capture the generalised geometry of type IIA string backgrounds with Ramond–Ramond fluxes and Romans mass. Each of these is associated with a BPS brane in type IIA: a D2, D4, or NS5-brane.
