Conformal field theory complexity from Euler-Arnold equations [PDF]
Journal of High Energy Physics, 2020 Defining complexity in quantum field theory is a difficult task, and the main challenge concerns going beyond free models and associated Gaussian states and operations.

Higher-dimensional conformal field theories in the Coulomb branch [PDF]
, 2010 We use the AdS/CFT correspondence to study flows of N=4 SYM to non-conformal theories. The dual geometries can be seen as sourced by a Wigner's semicircle distribution of D3 branes.

Open descendants in conformal field theory [PDF]
, 1997 Open descendants extend Conformal Field Theory to unoriented surfaces with boundaries. The construction rests on two types of generalizations of the fusion algebra. The first is needed even in the relatively simple case of diagonal models.

Global symmetry and conformal bootstrap in the two-dimensional $Q$-state Potts model
SciPost Physics, 2023 The Potts conformal field theory is an analytic continuation in the central charge of conformal field theory describing the critical two-dimensional $Q$-state Potts model.

Conformal defects from string field theory
Journal of High Energy Physics, 2021 Unlike conformal boundary conditions, conformal defects of Virasoro minimal models lack classification. Alternatively to the defect perturbation theory and the truncated conformal space approach, we employ open string field theory (OSFT) techniques to ...

Decoherence in Conformal Field Theory
Journal of High Energy Physics, 2020 Noise sources are ubiquitous in Nature and give rise to a description of quantum systems in terms of stochastic Hamiltonians. Decoherence dominates the noise-averaged dynamics and leads to dephasing and the decay of coherences in the eigenbasis of the ...

Complexity of warped conformal field theory
European Physical Journal C: Particles and Fields, 2023 Warped conformal field theories in two dimensions are exotic nonlocal, Lorentz violating field theories characterized by Virasoro–Kac–Moody symmetries and have attracted a lot of attention as candidate boundary duals to warped AdS $$_3$$ 3 spacetimes ...

Elements of celestial conformal field theory
Journal of High Energy Physics, 2022 In celestial holography, four-dimensional scattering amplitudes are considered as two-dimensional conformal correlators of a putative two-dimensional celestial conformal field theory (CCFT).

A note on commutation relation in conformal field theory
Journal of High Energy Physics, 2021 In this note, we explicitly compute the vacuum expectation value of the commutator of scalar fields in a d-dimensional conformal field theory on the cylinder.

On the dynamics of protected ramond ground states in the D1-D5 CFT
Journal of High Energy Physics, 2021 We examine the behavior of the Ramond ground states in the D1-D5 CFT after a deformation of the free-orbifold sigma model on target space ( T 4 $$ {\mathbbm{T}}^4 $$ ) N /S N by a marginal interaction operator.
