Conformal field theories are magical [PDF]
Physical Review B, 2021 "Magic" is the degree to which a state cannot be approximated by Clifford gates. We study mana, a measure of magic, in the ground state of the $\mathbb Z_3$ Potts model, and argue that it is a broadly useful diagnostic for many-body physics. In particular we find that the $q = 3$ ground state has large mana at the model's critical point, and that this ...

Holographic Complex Conformal Field Theories [PDF]
Physical Review Letters, 2020 The loss of criticality in the form of weak first-order transitions or the end of the conformal window in gauge theories can be described as the merging of two fixed points that move to complex values of the couplings. When the complex fixed points are close to the real axis, the system typically exhibits walking behavior with Miransky (or Berezinsky ...

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 ...

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

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).

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.

Boundary conformal field theory and a boundary central charge [PDF]
Journal of High Energy Physics, 2017 We consider the structure of current and stress tensor two-point functions in conformal field theory with a boundary. The main result of this paper is a relation between a boundary central charge and the coefficient of a displacement operator correlation

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.
