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.

Complexity change under conformal transformations in AdS3/CFT2

Journal of High Energy Physics, 2019
Using the volume proposal, we compute the change of complexity of holographic states caused by a small conformal transformation in AdS 3 /CF T 2. This computation is done perturbatively to second order.

Spectroscopy of fermionic operators in AdS/CFT [PDF]

, 2006
We compute the spectrum of color-singlet fermionic operators in the N=2 gauge theory on intersecting D3 and D7-branes using the AdS/CFT correspondence.

Holographic meson decays via worldsheet instantons

Journal of High Energy Physics, 2018
We study meson decays using instanton methods in two string models. The first model is the old string model in flat space which combines strings and massive particles and the second is the holographic, Sakai-Sugimoto model. Using the old string model, we

Probing the holographic dilaton

Journal of High Energy Physics, 2020
Many strongly coupled field theories admit a spectrum of gauge-invariant bound states that includes scalar particles with the same quantum numbers as the vacuum. The challenge naturally arises of how to characterise them. In particular, how can a dilaton

Integrability of classical strings dual for noncommutative gauge theories [PDF]

, 2014
We derive the gravity duals of noncommutative gauge theories from the Yang-Baxter sigma model description of the AdS_5xS^5 superstring with classical r-matrices.

Real-time gravitational replicas: formalism and a variational principle

Journal of High Energy Physics, 2021
This work is the first step in a two-part investigation of real-time replica wormholes. Here we study the associated real-time gravitational path integral and construct the variational principle that will define its saddle-points.

Holographic Fermi and Non-Fermi Liquids with Transitions in Dilaton Gravity [PDF]

, 2011
We study the two-point function for fermionic operators in a class of strongly coupled systems using the gauge-gravity correspondence. The gravity description includes a gauge field and a dilaton which determines the gauge coupling and the potential ...

Reflected entropy and entanglement negativity for holographic moving mirrors

Journal of High Energy Physics, 2022
We investigate the time evolution of reflected entropy and entanglement negativity for mixed state configurations involving two adjacent and disjoint intervals in the radiation flux of moving mirrors by utilizing the AdS/BCFT duality.

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
