Entanglement harvesting in the presence of a reflecting boundary
Journal of High Energy Physics, 2021 We study, in the framework of the entanglement harvesting protocol, the entanglement harvesting of both a pair of inertial and uniformly accelerated detectors locally interacting with vacuum massless scalar fields subjected to a perfectly reflecting ...

Worldline approach to quantum field theories on flat manifolds with boundaries [PDF]
Journal of High Energy Physics, 2007 We study a worldline approach to quantum field theories on flat manifolds with boundaries. We consider the concrete case of a scalar field propagating on R_+ x R^{D-1} which leads us to study the associated heat kernel through a one dimensional (worldline) path integral.

The reflection coefficient for minimal model conformal defects from perturbation theory
Journal of High Energy Physics, 2018 We consider a class of conformal defects in Virasoro minimal models that have been defined as fixed points of the renormalisation group and calculate the leading contribution to the reflection coefficient for these defects.

Protecting the conformal symmetry via bulk renormalization on Anti deSitter space [PDF]
, 2010 The problem of perturbative breakdown of conformal symmetry can be avoided, if a conformally covariant quantum field phi on d-dimensional Minkowski spacetime is viewed as the boundary limit of a quantum field Phi on d+1-dimensional anti-deSitter ...

Renyi relative entropies and renormalization group flows
Journal of High Energy Physics, 2018 Quantum Renyi relative entropies provide a one-parameter family of distances between density matrices, which generalizes the relative entropy and the fidelity. We study these measures for renormalization group flows in quantum field theory.

J.Phys.A41:304004,2008, 2008 The effect of boundary conditions on the vacuum structure of quantum field theories is analysed from a quantum information viewpoint. In particular, we analyse the role of boundary conditions on boundary entropy and entanglement entropy. The analysis of boundary effects on massless free field theories points out the relevance of boundary conditions as ...

Setting the quantum integrand of M-theory
, 2005 In anomaly-free quantum field theories the integrand in the bosonic functional integral--the exponential of the effective action after integrating out fermions--is often defined only up to a phase without an additional choice.

Two dimensional general covariance from three dimensions [PDF]
, 1993 A 3d generally covariant field theory having some unusual properties is described. The theory has a degenerate 3-metric which effectively makes it a 2d field theory in disguise.
