Boundary Quantum Field Theory on the Interior of the Lorentz Hyperboloid [PDF]
Communications in Mathematical Physics, 2012 We construct local, boost covariant boundary QFT nets of von Neumann algebras on the interior of the Lorentz hyperboloid LH = {x^2 - t^2 > R^2, x>0}, in the two-dimensional Minkowski spacetime. Our first construction is canonical, starting with a local conformal net on the real line, and is analogous to our previous construction of local boundary

Critical 1- and 2-point spin correlations for the O(2) model in 3d bounded domains
Journal of High Energy Physics, 2021 We study the critical properties of the 3d O(2) universality class in bounded domains through Monte Carlo simulations of the clock model. We use an improved version of the latter, chosen to minimize finite-size corrections at criticality, with 8 ...

Two point functions in defect CFTs
Journal of High Energy Physics, 2021 This paper is designed to be a practical tool for constructing and investigating two-point correlation functions in defect conformal field theory, directly in physical space, between any two bulk primaries or between a bulk primary and a defect primary ...

An Algebraic Construction of Boundary Quantum Field Theory [PDF]
Communications in Mathematical Physics, 2010 We build up local, time translation covariant Boundary Quantum Field Theory nets of von Neumann algebras A_V on the Minkowski half-plane M_+ starting with a local conformal net A of von Neumann algebras on the real line and an element V of a unitary semigroup E(A) associated with A.

O(N) models with boundary interactions and their long range generalizations
Journal of High Energy Physics, 2020 We study the critical properties of scalar field theories in d + 1 dimensions with O(N) invariant interactions localized on a d-dimensional boundary. By a combination of large N and epsilon expansions, we provide evidence for the existence of non-trivial

Harvesting correlations from vacuum quantum fields in the presence of a reflecting boundary
Journal of High Energy Physics, 2023 We explore correlations harvesting by two static detectors locally interacting with vacuum massless scalar fields in the presence of an infinite perfectly reflecting boundary.

Bootstrapping boundary-localized interactions
Journal of High Energy Physics, 2020 We study conformal boundary conditions for the theory of a single real scalar to investigate whether the known Dirichlet and Neumann conditions are the only possibilities.

Operator expansions, layer susceptibility and two-point functions in BCFT
Journal of High Energy Physics, 2020 We show that in boundary CFTs, there exists a one-to-one correspondence between the boundary operator expansion of the two-point correlation function and a power series expansion of the layer susceptibility.
