Mixed boundary conditions in quantum field theory
Journal of Mathematical Physics, 1991When quantum field theory is formulated in terms of transition amplitudes between initial and final configurations, it is important to impose mathematically consistent boundary conditions on the fields. The choice of boundary conditions is also important when dealing with elliptic complexes and index theorems on bounded manifolds.

Boundary conditions in quantum field theories
Foundations of Physics, 1993Several interesting and important quantum field theories must contain the coupling constant in the boundary conditions. The theories considered include quantum electrodynamics of spin-1/2 fermions and gauge field theories.

Quantum field theory with boundary conditions at the horizons
International Journal of Modern Physics D, 2021A 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.

Nontransparent boundaries in quantum field theory
Physica A: Statistical Mechanics and its Applications, 1992Abstract In quantum field theory a boundary which is totally transparent to a noninteracting field φ ceases to be so when φ is coupled to a second field constrained by that boundary.

QUANTUM LIOUVILLE FIELD THEORY ON A MANIFOLD WITH BOUNDARY
Modern Physics Letters A, 1998This letter studies the quantum Liouville field theory on a manifold with boundary. The boundary conformal Ward identity (CWI) is written and its semiclassical approximation is analyzed. This establishes a method of finding the accessory parameters of the theory with boundary.

Aspects of Integrable Quantum Field Theories with Boundaries
2001The purpose of the talk is to give the flavour of a dynamical argument which makes use of boundary states in order to calculate the dependence of certain quantities, such as reflection factors, on the coupling constants introduced at a boundary by integrable boundary conditions. The idea is to consider the boundary state spectrum from two complementary

Determinants of Elliptic Boundary Problems in Quantum Field Theory
2001We review some recent advances in understanding the zeta determinant of an elliptic boundary value problem for the Dirac operator. We discuss a recent adiabatic pasting formula for the determinant with respect to a partition of the underlying manifold, and outline some of the applications to geometric anomalies.
