Second order quantum corrections to the classical reflection factor of the sinh-Gordon model [PDF]
, 2001 The sinh-Gordon model on a half-line with integrable boundary conditions is considered in low order perturbation theory developed in affine Toda field theory.

Tunneling in quantum wires: A boundary conformal field theory approach [PDF]
Nuclear Physics B, 1994 Tunneling through a localized barrier in a one-dimensional interacting electron gas has been studied recently using Luttinger liquid techniques. Stable phases with zero or unit transmission occur, as well as critical points with universal fractional transmission whose properties have only been calculated approximately, using a type of ``$ $-expansion''

On local boundary CFT and non-local CFT on the boundary
, 2004 The holographic relation between local boundary conformal quantum field theories (BCFT) and their non-local boundary restrictions is reviewed, and non-vacuum BCFT's, whose existence was conjectured previously, are constructed.Comment: 16 pages ...

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.

A Lorentzian inversion formula for defect CFT
Journal of High Energy Physics, 2020 We present a Lorentzian inversion formula valid for any defect CFT that extracts the bulk channel CFT data as an analytic function of the spin variable.

Defect extremal surface as the holographic counterpart of Island formula
Journal of High Energy Physics, 2021 We propose defect extremal surface as the holographic counterpart of boundary quantum extremal surface. The defect extremal surface is defined by minimizing the Ryu-Takayanagi surface corrected by the defect theory.

Left-Right Entanglement Entropy of Boundary States
, 2014 We study entanglement entropy of boundary states in a free bosonic conformal field theory. A boundary state can be thought of as composed of a particular combination of left and right-moving modes of the two-dimensional conformal field theory.

Analytic bootstrap for boundary CFT
Journal of High Energy Physics, 2019 We propose a method to analytically solve the bootstrap equation for two point functions in boundary CFT. We consider the analytic structure of the correlator in Lorentzian signature and in particular the discontinuity of bulk and boundary conformal ...

Reverse Engineering Quantum Field Theory
, 2012 An approach to the foundations of quantum theory is advertised that proceeds by "reverse engineering" quantum field theory. As a concrete instance of this approach, the general boundary formulation of quantum theory is outlined.Comment: 5 pages, LaTeX ...

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
