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 ...

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 ...

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.

Rationality in conformal field theory [PDF]
Communications in Mathematical Physics, 1988 The Hilbert space of a conformal field theory (CFT) is a positive-energy representation of the direct sum of two commuting copies of the Virasoro algebra, and hence decomposes \[ H=\oplus_{h,\bar h\geq 0}V(h,c)\oplus \bar V(\bar h,c) \tag{*} \] where \(V(h,c)\) is the irreducible representation of the Virasoro algebra with highest weight \(h\) and ...

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

Dynamics of R-neutral Ramond fields in the D1-D5 SCFT
Journal of High Energy Physics, 2021 We describe the effect of the marginal deformation of the N $$ \mathcal{N} $$ = (4, 4) super-conformal (T 4) N /S N orbifold theory on a doublet of R-neutral twisted Ramond fields, in the large-N approximation. Our analysis of their dynamics explores the

Markov Property of the Conformal Field Theory Vacuum and the a Theorem. [PDF]
Physical Review Letters, 2017 We use strong subadditivity of entanglement entropy, Lorentz invariance, and the Markov property of the vacuum state of a conformal field theory to give new proof of the irreversibility of the renormalization group in d=4 space-time dimensions-the a ...
