Mixed boundary conditions in quantum field theory

Journal of Mathematical Physics, 1991
When 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, 1993
Several 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.

Nontransparent boundaries in quantum field theory

Physica A: Statistical Mechanics and its Applications, 1992
Abstract 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 field theory with boundary conditions at the horizons

International Journal of Modern Physics D, 2021
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.
