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

One-loop universality of holographic codes
Journal of High Energy Physics, 2020 Recent work showed holographic error correcting codes to have simple universal features at O(1/G). In particular, states of fixed Ryu-Takayanagi (RT) area in such codes are associated with flat entanglement spectra indicating maximal entanglement between

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 ...

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.

Bjorken Flow of the quark-gluon plasma and Gauge/Gravity Correspondence
, 2009 The contribution presents a brief summary of the Gauge/Gravity approach to the study of hydrodynamic flow of the quark-gluon plasma formed in heavy-ion collisions, in a boost-invariant setting (Bjorken flow). Considering the ideal case of a supersymmetric Yang-Mills theory for which the AdS/CFT correspondence gives a precise form of the Gauge/Gravity ...

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.

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.

Gauge/Gravity Duality and Some Applications [PDF]
, 2010 We discuss the AdS/CFT correspondence in which space-time emerges from an interacting theory of D-branes and open strings. These ideas have a historical continuity with QCD which is an interacting theory of quarks and gluons.

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.
