Instanton R-matrix and $$ \mathcal{W} $$-symmetry [PDF]

open access: yes, 2019
We study the relation between $\mathcal{W}_{1+\infty}$ algebra and Arbesfeld-Schiffmann-Tsymbaliuk Yangian using the Maulik-Okounkov R-matrix. The central object linking these two pictures is the Miura transformation.

W$$ \mathcal{W} $$ symmetry in six dimensions [PDF]

open access: yes, 2014
A bstractSix-dimensional conformal field theories with (2, 0) supersymmetry are shown to possess a protected sector of operators and observables that are isomorphic to a two-dimensional chiral algebra. We argue that the chiral algebra associated to a (2,

Multifractality and conformal invariance at 2D metal-insulator transition in the spin-orbit symmetry class. [PDF]

open access: yesPhysical Review Letters, 2006
We study the multifractality (MF) of critical wave functions at boundaries and corners at the metal-insulator transition (MIT) for noninteracting electrons in the two-dimensional (2D) spin-orbit (symplectic) universality class.

Relationship between symmetry protected topological phases and boundary conformal field theories via the entanglement spectrum [PDF]

open access: yes, 2016
Quantum phase transitions out of a symmetry-protected topological (SPT) phase in (1  +  1) dimensions into an adjacent, topologically distinct SPT phase protected by the same symmetry or a trivial gapped phase, are typically described by a conformal ...

Recursion relations for 5-point conformal blocks

open access: yesJournal of High Energy Physics, 2021
We consider 5-point functions in conformal field theories in d > 2 dimensions. Using weight-shifting operators, we derive recursion relations which allow for the computation of arbitrary conformal blocks appearing in 5-point functions of scalar operators,

On local and integrated stress-tensor commutators

open access: yesJournal of High Energy Physics, 2021
We discuss some general aspects of commutators of local operators in Lorentzian CFTs, which can be obtained from a suitable analytic continuation of the Euclidean operator product expansion (OPE).

On the existence of an L∞ structure for the super-Virasoro algebra

open access: yesJournal of High Energy Physics, 2019
The appearance of L∞ structures for supersymmetric symmetry algebras in two-dimensional conformal field theories is investigated. Looking at the simplest concrete example of the N = 1 $$ \mathcal{N}=1 $$ super-Virasoro algebra in detail, we investigate ...

Conformal four-point correlation functions from the operator product expansion

open access: yesJournal of High Energy Physics, 2020
We show how to compute conformal blocks of operators in arbitrary Lorentz representations using the formalism described in [1, 2] and present several explicit examples of blocks derived via this method.

On the light-ray algebra in conformal field theories

open access: yesJournal of High Energy Physics, 2022
We analyze the commutation relations of light-ray operators in conformal field theories. We first establish the algebra of light-ray operators built out of higher spin currents in free CFTs and find explicit expressions for the corresponding structure ...

Crossing symmetry and Higher spin towers

open access: yesJournal of High Energy Physics, 2017
We consider higher spin operators in weakly coupled gauge conformal field theories. Crossing symmetry of mixed scalar correlators relates different higher spin towers and we study the consequences for the spectrum and structure constants of higher spin ...
