Algebraic orbifold conformal field theories [PDF]
Proceedings of the National Academy of Sciences, 2000 The unitary rational orbifold conformal field theories in the algebraic quantum field theory and subfactor theory framework are formulated. Under general conditions, it is shown that the orbifold of a given unitary rational conformal field theory generates a unitary modular category. Many new unitary modular categories are obtained.

Genus-one string amplitudes from conformal field theory
Journal of High Energy Physics, 2019 We explore and exploit the relation between non-planar correlators in N $$ \mathcal{N} $$ = 4 super-Yang-Mills, and higher-genus closed string amplitudes in type IIB string theory.

Conformal field theories in a magnetic field
Physical Review ResearchWe study the properties of 2+1d conformal field theories (CFTs) in a background magnetic field. Using generalized particle-vortex duality, we argue that in many cases of interest the theory becomes gapped, which allows us to make a number of predictions for the magnetic response, background monopole operators, and more. Explicit calculations at large N

Conformal mapping of non-Lorentzian geometries in SU(1, 2) Conformal Field Theory
Journal of High Energy PhysicsWe realize an explicit conformal mapping between the state and operator pictures in a class of (2 + 1)-dimensional non-Lorentzian field theories with SU(1, 2) × U(1) conformal symmetry.

Gravitational dressing of 3D conformal Galileon
Physics Letters B, 2019 Could a conformal Galileon be describing a gauge mode of a broader diffeomorphism invariant theory? We answer this question affirmatively in 3D by using a coset construction for a nonlinearly realized conformal symmetry.

1d conformal field theory and dispersion relations
Journal of High Energy PhysicsWe study conformal field theory in d = 1 space-time dimensions. We derive a dispersion relation for the 4-point correlation function of identical bosons and fermions, in terms of the double discontinuity. This extends the conformal dispersion relation of

On the Real Part of a Conformal Field Theory
Universe, 2018 Every conformal field theory has the symmetry of taking each field to its adjoint. We consider here the quotient (orbifold) conformal field theory obtained by twisting with respect to this symmetry.

On marginal operators in boundary conformal field theory
Journal of High Energy Physics, 2019 The presence of a boundary (or defect) in a conformal field theory allows one to generalize the notion of an exactly marginal deformation. Without a boundary, one must find an operator of protected scaling dimension ∆ equal to the space-time dimension d ...

Effective field theory for chaotic CFTs
Journal of High Energy Physics, 2018 We derive an effective field theory for general chaotic two-dimensional conformal field theories with a large central charge. The theory is a specific and calculable instance of a more general framework recently proposed in [1].
