Entanglement Hamiltonians in two-dimensional conformal field theory [PDF]
, 2016 We enumerate the cases in 2d conformal field theory where the logarithm of the reduced density matrix (the entanglement or modular Hamiltonian) may be written as an integral over the energy-momentum tensor times a local weight.

Conformal field theory and the web of quantum chaos diagnostics [PDF]
Journal of High Energy Physics, 2019 We study three prominent diagnostics of chaos and scrambling in the context of two-dimensional conformal field theory: the spectral form factor, out-of-time-ordered correlators, and unitary operator entanglement.

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

PCT Theorem, Wightman Axioms and Conformal Bootstrap [PDF]
, 2021 The axiomatic Wightman formulation for nonderivative conformal field theory is adopted to derive conformal bootstrap equation for the four point function. The equivalence between PCT theorem and {\it weak local commutativity}, due to Jost, play a very crucial role in axiomatic field theory.

AdS field theory from conformal field theory [PDF]
Journal of High Energy Physics, 2013 Abstract We provide necessary and sufficient conditions for a Conformal Field Theory to have a description in terms of a perturbative Effective Field Theory in AdS. The first two conditions are well-known: the existence of a perturbative ‘1/N ’ expansion and an approximate Fock space of states generated by a finite number of low ...

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.

Conformal field theory out of equilibrium: a review [PDF]
, 2016 We provide a pedagogical review of the main ideas and results in non-equilibrium conformal field theory and connected subjects. These concern the understanding of quantum transport and its statistics at and near critical points.

A scattering amplitude in Conformal Field Theory [PDF]
Journal of High Energy Physics, 2020 Abstract We define form factors and scattering amplitudes in Conformal Field Theory as the coefficient of the singularity of the Fourier transform of time-ordered correlation functions, as p2 → 0. In particular, we study a form factor F(s, t, u) obtained from a four-point function of identical scalar primary operators. We show that

Quantum dynamics in sine-square deformed conformal field theory: Quench from uniform to nonuniform conformal field theory [PDF]
Physical review B, 2018 In this work, motivated by the sine-square deformation (SSD) for (1+1)-dimensional quantum critical systems, we study the non-equilibrium quantum dynamics of a conformal field theory (CFT) with SSD, which was recently proposed to have continuous energy ...
