New Advancements in AdS/CFT in Lower Dimensions [PDF]

open access: yes, 2021
We review recent developments in the study of the AdS/CFT correspondence in lower dimensions. We start by summarising the classification of AdS3×S2 solutions in massive type IIA supergravity with (0, 4) supersymmetries and the construction of their 2D ...

On the hydrodynamics of unstable excitations

open access: yesJournal of High Energy Physics, 2020
The generalized hydrodynamic (GHD) approach has been extremely successful in describing the out-of-equilibrium properties of a great variety of integrable many-body quantum systems.

Lower Bound on the Energy Density in Classical and Quantum Field Theories [PDF]

open access: yes, 2017
A novel method for deriving energy conditions in stable field theories is described. In a local classical theory with one spatial dimension, a local energy condition always exists.

Capacity of entanglement in local operators

open access: yesJournal of High Energy Physics, 2021
We study the time evolution of the excess value of capacity of entanglement between a locally excited state and ground state in free, massless fermionic theory and free Yang-Mills theory in four spacetime dimensions.

Entanglement content of quantum particle excitations. Part II. Disconnected regions and logarithmic negativity

open access: yesJournal of High Energy Physics, 2019
In this paper we study the increment of the entanglement entropy and of the (replica) logarithmic negativity in a zero-density excited state of a free massive bosonic theory, compared to the ground state.

The complex sinh-Gordon model: form factors of descendant operators and current-current perturbations

open access: yesJournal of High Energy Physics, 2019
We study quasilocal operators in the quantum complex sinh-Gordon theory in the form factor approach. The free field procedure for descendant operators is developed by introducing the algebra of screening currents and related algebraic objects.

Conformal bootstrap deformations

open access: yesJournal of High Energy Physics, 2022
We explore the space of extremal functionals in the conformal bootstrap. By recasting the bootstrap problem as a set of non-linear equations parameterized by the CFT data, we find an efficient algorithm for converging to the extremal solution ...

Light-ray moments as endpoint contributions to modular Hamiltonians

open access: yesJournal of High Energy Physics, 2021
We consider excited states in a CFT, obtained by applying a weak unitary perturbation to the vacuum. The perturbation is generated by the integral of a local operator J (n) of modular weight n over a spacelike surface passing through x = 0.

On twistors and conformal field theories from six dimensions [PDF]

open access: yes, 2013
We discuss chiral zero-rest-mass field equations on six-dimensional space-time from a twistorial point of view. Specifically, we present a detailed cohomological analysis, develop both Penrose and Penrose-Ward transforms, and analyse the corresponding ...

Logarithmic negativity in quantum Lifshitz theories

open access: yesJournal of High Energy Physics, 2020
We investigate quantum entanglement in a non-relativistic critical system by calculating the logarithmic negativity of a class of mixed states in the quantum Lifshitz model in one and two spatial dimensions.
