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.

On Twistors and Conformal Field Theories from Six Dimensions [PDF]

open access: yes, 2011
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 ...

How planar superconductors cure their infrared divergences

open access: yesJournal of High Energy Physics, 2022
Planar superconductors, emerging in thin films with thickness comparable to the superconducting coherence length, differ crucially from their bulk counterparts.

$D$-Dimensional Gravity from $(D+1)$ Dimensions [PDF]

open access: yes, 1995
We generalise Wesson's procedure, whereby vacuum $(4+1)-$dimensional field equations give rise to $(3+1)-$dimensional equations with sources, to arbitrary dimensions. We then employ this generalisation to relate the usual $(3+1)-$dimensional vacuum field

Some lower dimensional quantum field theories reduced from Chern-Simons gauge theories [PDF]

open access: yesPhysical Review D
We study symmetry reductions in the context of Euclidean Chern-Simons gauge theories to obtain lower dimensional field theories. Symmetry reduction in certain gauge theories is a common tool for obtaining explicit soliton solutions.

Metric approach to a T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ -like deformation in arbitrary dimensions

open access: yesJournal of High Energy Physics, 2022
We consider a one-parameter family of composite fields — bi-linear in the components of the stress-energy tensor — which generalise the T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ operator to arbitrary space-time dimension d ≥ 2. We show that they induce

Higher Structure of Chiral Symmetry [PDF]

open access: yesCommunications in Mathematical Physics, 2023
A recent development in our understanding of the theory of quantum fields is the fact that familiar gauge theories in spacetime dimensions greater than two can have non-invertible symmetries generated by topological defects.

Implications of ANEC for SCFTs in four dimensions [PDF]

open access: yesJournal of High Energy Physics, 2019
We explore consequences of the Averaged Null Energy Condition (ANEC) for scaling dimensions ∆ of operators in four-dimensional N $$ \mathcal{N} $$ = 1 superconformal field theories.

Entanglement and confinement in coupled quantum systems

open access: yesJournal of High Energy Physics, 2021
We study some general properties of coupled quantum systems. We consider simple interactions between two copies of identical Hamiltonians such as the SYK model, Pauli spin chains with random magnetic field and harmonic oscillators.

Carving Out the Space of 4D CFTs [PDF]

open access: yes, 2011
We introduce a new numerical algorithm based on semidefinite programming to efficiently compute bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal and N=1 superconformal field theories.
