Axiomatic Conformal Field Theory [PDF]
Communications in Mathematical Physics, 2000 A new rigorous approach to conformal field theory is presented. The basic objects are families of complex-valued amplitudes, which define a meromorphic conformal field theory (or chiral algebra) and which lead naturally to the definition of topological vector spaces, between which vertex operators act as continuous operators.

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 ...

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 ...

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 ...

Quantum gravity from conformal field theory
Journal of High Energy Physics, 2018 We bootstrap loop corrections to AdS5 supergravity amplitudes by enforcing the consistency of the known classical results with the operator product expansion of N $$ \mathcal{N} $$ = 4 super Yang-Mills theory.

Non-relativistic conformal field theory in the presence of boundary
Journal of High Energy Physics, 2022 We study non-relativistic conformal field theory on a flat space in the presence of a planar boundary. We compute correlation functions of primary operators and obtain the expression for the boundary conformal block.

Hidden conformal symmetry for Kerr-Newman-NUT-AdS black holes
Nuclear Physics B, 2020 We find the non-extremal Kerr-Newman-NUT-AdS black holes are holographically dual to the hidden two-dimensional conformal field theories. We explicitly construct two different conformal field theories (known as the J and Q pictures) dual to the black ...

On non-supersymmetric conformal manifolds: field theory and holography
Journal of High Energy Physics, 2017 We discuss the constraints that a conformal field theory should enjoy to admit exactly marginal deformations, i.e. to be part of a conformal manifold. In particular, using tools from conformal perturbation theory, we derive a sum rule from which one can ...
