Constructing AdS2 flow geometries
Journal of High Energy Physics, 2021 We consider two-dimensional geometries flowing away from an asymptotically AdS2 spacetime. Macroscopically, flow geometries and their thermodynamic properties are studied from the perspective of dilaton-gravity models.

The Markov gap in the presence of islands
Journal of High Energy Physics, 2023 The Markov gap [1], namely the difference between reflected entropy and mutual information, is explicitly computed in the defect extremal surface model, JT gravity, and the generic 2d extremal black holes, in vacuum states.

Gauge-gravity correspondence in an accelerating universe [PDF]
Physical Review D, 2002 We discuss time-dependent backgrounds of type IIB supergravity realizing gravitation duals of gauge theories formulated in de Sitter space-time as a tool of embedding de Sitter in a supergravity. We show that only the gravitational duals to non-conformal gauge theories are sensitive to a specific value of a Hubble parameter.

Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]
, 2010 The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...

The Newman-Penrose map and the classical double copy
Journal of High Energy Physics, 2020 Gauge-gravity duality is arguably our best hope for understanding quantum gravity. Considerable progress has been made in relating scattering amplitudes in certain gravity theories to those in gauge theories — a correspondence dubbed the double copy ...

Rényi entropies and area operator from gravity with Hayward term
Journal of High Energy Physics, 2020 In the context of the holographic duality, the entanglement entropy of ordinary QFT in a subregion in the boundary is given by a quarter of the area of an minimal surface embedded in the bulk spacetime.

Journal of High Energy Physics, 2017 The Nambu-Goldstone (NG) bosons of the SYK model are described by a coset space Diff/SL(2, ℝ), where Diff, or Virasoro group, is the group of diffeomorphisms of the time coordinate valued on the real line or a circle. It is known that the coadjoint orbit

Time-independence of gravitational Rényi entropies and unitarity in quantum gravity
Journal of High Energy Physics, 2021 The Hubeny-Rangamani-Takayanagi surface γ HRT computing the entropy S(D) of a domain of dependence D on an asymptotically AdS boundary is known to be causally inaccessible from D. We generalize this gravitational result to higher replica numbers n > 1 by
