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).

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 ...

The Origin of space-time as W symmetry breaking in string theory [PDF]
, 1992 Physics in the neighbourhood of a space-time metric singularity is described by a world-sheet topological gauge field theory which can be represented as a twisted N = 2 super-conformal Wess-Zumino model with a W 1+∞ ⊗W 1+∞ bosonic symmetry.

Ward identities of W∞ symmetry in Liouville theory coupled to cM < 1 matter [PDF]
, 1993 We investigate the Ward identities of the W ∞ symmetry in the Liouville theory coupled to the ( p , q ) conformal matter. The correlation functions are defined by applying the analytic continuation procedure for the matter sector as well as the Liouville

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 ...

Wronskian indices and rational conformal field theories
Journal of High Energy Physics, 2021 The classification scheme for rational conformal field theories, given by the Mathur-Mukhi-Sen (MMS) program, identifies a rational conformal field theory by two numbers: (n, l). n is the number of characters of the rational conformal field theory.

The role of complex structures in w-symmetry [PDF]
, 2000 In a symplectic framework, the infinitesimal action of symplectomorphisms together with suitable reparametrizations of the two dimensional complex base space generate some type of W-algebras.

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

Conformal four-point correlation functions from the operator product expansion
Journal 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.
