Boundary bound states in integrable quantum field theories [PDF]
, 2000 The purpose of this talk is to sketch some recent progress which has been made in calculating non-perturbatively the reflection factors for the sinh-Gordon model restricted to a half-line by integrable boundary conditions. The essential idea is to calculate the energy spectrum of boundary breathers in two independent ways; firstly by using the boundary

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.

Quantum field theory with boundary conditions at the horizons
International Journal of Modern Physics D, 2023 A procedure to derive a unitary evolution law for a quantised black hole has been proposed by the author. The proposal implies several assumptions, which seem almost unavoidable to this author. We start off with the question how to describe the energy eigenstates of a black hole.

Quantum field theories on manifolds with curved boundaries: Scalar fields [PDF]
Nuclear Physics B, 1993 A framework allowing for perturbative calculations to be carried out for quantum field theories with arbitrary smoothly curved boundaries is described. It is based on an expansion of the heat kernel derived earlier for arbitrary mixed Dirichlet and Neumann boundary conditions.

Towards quantum field theory on spacetimes with boundaries [PDF]
The Fourteenth Marcel Grossmann Meeting, 2017 Algebraic quantization has been applied on the class of globally hyperbolic spacetime for many decades, leading to remarkable results. Nonetheless, the presence of a boundary calls for a separate treatment, since, in general, it breaks global hyperbolicity and it requires the introduction of boundary conditions to the field equation. Although a general
