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

Higher Structure of Chiral Symmetry [PDF]
Communications 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.

Entanglement and confinement in coupled quantum systems
Journal 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.

Symmetry enhancement and duality walls in 5d gauge theories [PDF]
Journal of High Energy Physics, 2020 Gauge theories in four dimensions can exhibit interesting low energy phenomena, such as infrared enhancements of global symmetry. We explore a class of 4d N\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts ...

On the hydrodynamics of unstable excitations
Journal 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.

Journal 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

$D$-Dimensional Gravity from $(D+1)$ Dimensions [PDF]
, 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]
Physical Review DWe 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.

A note on the S-matrix bootstrap for the 2d O(N) bosonic model
Journal of High Energy Physics, 2018 In this work we apply the S-matrix bootstrap maximization program to the 2d bosonic O(N) integrable model which has N species of scalar particles of mass m and no bound states.

Carving Out the Space of 4D CFTs [PDF]
, 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.
