On non-linear W-infinity symmetry of generalized Liouville and conformal Toda models [PDF]
Physics Letters B, 1993 Invariance under non-linear ${\sf {\hat W}}_{\infty}$ algebra is shown for the two-boson Liouville type of model and its algebraic generalizations, the extended conformal Toda models. The realization of the corresponding generators in terms of two boson currents within KP hierarchy is presented.

Pseudo Entropy in U(1) gauge theory
Journal of High Energy Physics, 2022 We study the properties of pseudo entropy, a new generalization of entanglement entropy, in free Maxwell field theory in d = 4 dimension. We prepare excited states by the different components of the field strengths located at different Euclidean times ...

LIE SUPERALGEBRA AND EXTENDED TOPOLOGICAL CONFORMAL SYMMETRY IN NON-CRITICAL W3-STRINGS [PDF]
Modern Physics Letters A, 1994 We obtain a new free field realization of N = 2 super W3-algebra using the technique of quantum Hamiltonian reduction. The construction is based on a particular choice of the simple root system of the affine Lie superalgebra sl (3|2)(1) associated with a non-standard sl (2) embedding.

Higher-point conformal blocks in the comb channel
Journal of High Energy Physics, 2020 We compute M -point conformal blocks with scalar external and exchange operators in the so-called comb configuration for any M in any dimension d. Our computation involves repeated use of the operator product expansion to increase the number of external ...

Momentum space parity-odd CFT 3-point functions
Journal of High Energy Physics, 2021 We study the parity-odd sector of 3-point functions comprising scalar operators and conserved currents in conformal field theories in momentum space. We use momentum space conformal Ward identities as well as spin-raising and weight-shifting operators to

The Lorentzian inversion formula and the spectrum of the 3d O(2) CFT
Journal of High Energy Physics, 2020 We study the spectrum and OPE coefficients of the three-dimensional critical O(2) model, using four-point functions of the leading scalars with charges 0, 1, and 2 (s, ϕ, and t).

Recursion relations for 5-point conformal blocks
Journal 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
Journal 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
Journal 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 ...
