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 ...

On the light-ray algebra in conformal field theories
Journal 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 ...

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).

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

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 ...

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 ...

Crossing symmetry and Higher spin towers
Journal 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 ...

Dimensional reduction of higher-point conformal blocks
Journal of High Energy Physics, 2021 Recently, with the help of Parisi-Sourlas supersymmetry an intriguing relation was found expressing the four-point scalar conformal block of a (d − 2)-dimensional CFT in terms of a five-term linear combination of blocks of a d-dimensional CFT, with ...
