A holographic inequality for N = 7 regions

Journal of High Energy Physics, 2023
In holographic duality, boundary states that have semiclassical bulk duals must obey inequalities, which bound their subsystems’ von Neumann entropies. Hitherto known inequalities constrain entropies of reduced states on up to N = 5 disjoint subsystems ...

Freelance holography, part I: Setting boundary conditions free in gauge/gravity correspondence

SciPost Physics
We explore AdS/CFT duality in the large $N$ limit, where the duality reduces to gauge/gravity correspondence, from the viewpoint of covariant phase space formalism (CPSF).

Can one hear the shape of a wormhole?

Journal of High Energy Physics, 2022
A large class of flat big bang-big crunch cosmologies with negative cosmological constant are related by analytic continuation to asymptotically AdS traversable wormholes with planar cross section.

Information geometry encoded in bulk geometry

Journal of High Energy Physics, 2020
We study how information geometry is described by bulk geometry in the gauge/gravity correspondence. We consider a quantum information metric that measures the distance between the ground states of a CFT and a theory obtained by perturbing the CFT.

Generalized Recursion Relations for Correlators in the Gauge-Gravity Correspondence [PDF]

Physical Review Letters, 2011
We show that a generalization of the Britto-Cachazo-Feng-Witten recursion relations gives a new and efficient method of computing correlation functions of the stress tensor or conserved currents in conformal field theories with an (d+1)-dimensional anti-de Sitter space dual, for d≥4, in the limit where the bulk theory is approximated by tree-level Yang-

Velocity-induced heavy quarkonium dissociation using the gauge-gravity correspondence [PDF]

Physical Review D, 2015
Using the gauge-gravity duality we have obtained the potential between a heavy quark and an antiquark pair, which is moving perpendicular to the direction of orientation, in a strongly-coupled supersymmetric hot plasma. For the purpose we work on a metric in the gravity side, {\em viz.} OKS-BH geometry, whose dual in the gauge theory side runs with the

Purification complexity without purifications

Journal of High Energy Physics, 2021
We generalize the Fubini-Study method for pure-state complexity to generic quantum states by taking Bures metric or quantum Fisher information metric (QFIM) on the space of density matrices as the complexity measure.

D-instantons on orbifolds and gauge/gravity correspondence [PDF]

Fortschritte der Physik, 2002
D-instantons are used to probe the near-horizon geometry of D3-branes systems on orbifold spaces. For fractional D3-branes, D-instanton calculus correctly reproduces the gauge beta-function and U(1)_R anomaly of the corresponding N=2 non-conformal Super Yang-Mills theories. For D3-branes wrapping the orbifold singularity, D-instantons can be identified

On the chaos bound in rotating black holes

Journal of High Energy Physics, 2019
We study out-of-time-order correlators (OTOCs) of rotating BTZ black holes using two different approaches: the elastic eikonal gravity approximation, and the Chern-Simons formulations of 3-dimensional gravity.
