A New Property of the Electromagnetic/Yang-Mills-Conformal Gravity System in Spherical Symmetry
, 2019 We find a new property in $W^2$-conformal gravity in spherical symmetry. We demonstrate that the charge of the electromagnetic field varies with respect to the partial scaling symmetry (conformal transformations in subspaces of a spacetime) in the ...

2D CFT blocks for the 4D class $\mathcal{S}_k$ theories [PDF]
, 2017 This is the first in a series of papers on the search for the 2D CFT description of a large class of 4D $\mathcal{N} = 1$ gauge theories. Here, we identify the 2D CFT symmetry algebra and its representations, namely the conformal blocks of the Virasoro/W-

Conformal-field-theory approach to the two-impurity Kondo problem: Comparison with numerical renormalization-group results. [PDF]
Physical Review B (Condensed Matter), 1994 Numerical renormalization-group and conformal-field-theory work indicate that the two-impurity Kondo Hamiltonian has a non-Fermi-liquid critical point separating the Kondo-screening phase from the interimpurity singlet phase when particle-hole (P-H ...

Journal of High Energy Physics, 2019 We study the Virasoro conformal block decomposition of the genus two partition function of a two-dimensional CFT by expanding around a ℤ3-invariant Riemann surface that is a three-fold cover of the Riemann sphere branched at four points, and explore ...

The analytic bootstrap equations of non-diagonal two-dimensional CFT
Journal of High Energy Physics, 2018 Under the assumption that degenerate fields exist, diagonal CFTs such as Liouville theory can be solved analytically using the conformal bootstrap method. Here we generalize this approach to non-diagonal CFTs, i.e.

Conformal invariance, multifractality, and finite-size scaling at Anderson localization transitions in two dimensions [PDF]
, 2009 We generalize universal relations between the multifractal exponent 0 for the scaling of the typical wave function magnitude at a (Anderson) localization-delocalization transition in two dimensions and the corresponding critical finite size scaling ...

Journal of High Energy Physics, 2020 We study the 3-parametric family of vertex operator algebras based on the Grassmannian coset CFT u $$ \mathfrak{u} $$ (M + N ) k /( u $$ \mathfrak{u} $$ (M ) k × u $$ \mathfrak{u} $$ (N ) k ).

Dispersion relations and exact bounds on CFT correlators
Journal of High Energy Physics, 2021 We derive new crossing-symmetric dispersion formulae for CFT correlators restricted to the line. The formulae are equivalent to the sum rules implied by what we call master functionals, which are analytic extremal functionals which act on the crossing ...

Galilean contractions of $W$-algebras
, 2017 Infinite-dimensional Galilean conformal algebras can be constructed by contracting pairs of symmetry algebras in conformal field theory, such as $W$-algebras.

Logarithmic extensions of minimal models: characters and modular transformations [PDF]
, 2006 We study logarithmic conformal field models that extend the (p,q) Virasoro minimal models. For coprime positive integers $p$ and $q$, the model is defined as the kernel of the two minimal-model screening operators.
