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.

Triangle Anomalies from Einstein Manifolds
, 2006 The triangle anomalies in conformal field theory, which can be used to determine the central charge a, correspond to the Chern-Simons couplings of gauge fields in AdS under the gauge/gravity correspondence. We present a simple geometrical formula for the

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.

Advanced Functional Materials, EarlyView.Geometric multi‐bit patterning based on dynamic wetting and dewetting phenomena creates roulette‐like Physical Unclonable Function (PUF) labels with stochastic yet deterministic properties. This method leverages the solutal‐Marangoni effect for high randomness while achieving deterministic multinary patterns through polygonal confinement of binary ...

On multi-field flows in gravity and holography
Journal of High Energy Physics, 2018 We perform a systematic analysis of flow-like solutions in theories of Einstein gravity coupled to multiple scalar fields, which arise as holographic RG flows as well as in the context of cosmological solutions driven by scalars.

Double holography in string theory
Journal of High Energy Physics, 2022 We develop the notion of double holography in Type IIB string theory realizations of braneworld models. The Type IIB setups are based on the holographic duals of 4d BCFTs comprising 4d N $$ \mathcal{N} $$ = 4 SYM on a half space coupled to 3d N ...

Autonomous Control of Extrusion Bioprinting Using Convolutional Neural Networks
Advanced Functional Materials, EarlyView.This work presents a novel computer vision system for high‐fidelity monitoring of extrusion‐based bioprinting and a correction system utilizing convolutional neural networks for error mitigation. This system has demonstrated high detection accuracy and extrusion correction abilities that advance the state of the art toward accelerated printing ...

On the GKP Vacuum in Gauge/Gravity Correspondences
, 2014 Within the framework of the AdS5/CFT4 correspondence, the GKP string living on a AdS5 x S5 background finds a counterpart in the anti-ferromagnetic vacuum state for the spin chain, fruitfully employed to investigate the dual N=4 SYM superconformal gauge theory.

Advanced Functional Materials, EarlyView.The study explores for the first time the use of polyvinyl butyral (PVB), particularly recycled PVB, as a sustainable binder for Li/Na‐based electrodes in the framework of the H2020 SUNRISE EU project. Findings revealed that electrodes bound with a sustainable PAA/PVB mixture demonstrated exceptional rate capability and high initial Coulombic ...

TransverseDiff gravity is to scalar-tensor as unimodular gravity is to General Relativity
, 2012 Transverse Diffeomorphism (TDiff) theories are well-motivated theories of gravity from the quantum perspective, which are based upon a gauge symmetry principle.
