Analytic Results for a PT-symmetric Optical Structure
H. F. Jones
Propagation of light through media with a complex refractive index in which gain and loss are engineered to be symmetric has many remarkable features. In particular the usual…
PT-Symmetric Sinusoidal Optical Lattices at the Symmetry-Breaking Threshold
Eva-Maria Graefe, H. F. Jones
The symmetric potential has a completely real spectrum for , and begins to develop complex eigenvalues for . At the symmetry-brea…
Green Functions for the Wrong-Sign Quartic
H. F. Jones
It has been shown that the Schwinger-Dyson equations for non-Hermitian theories implicitly include the Hilbert-space metric. Approximate Green functions for such theories may thus…
Which Green Functions Does the Path Integral for Quasi-Hermitian Hamiltonians Represent?
H. F. Jones, R. J. Rivers
In the context of quasi-Hermitian theories, which are non-Hermitian in the conventional sense, but can be made Hermitian by the introduction of a dynamically-determined metric ,…
Interface between Hermitian and non-Hermitian Hamiltonians in a model calculation
H. F. Jones
We consider the interaction between the Hermitian world, represented by a real delta-function potential , and the non-Hermitian world, represented by a PT-symmetric pair of…
Dual PT-Symmetric Quantum Field Theories
Carl M. Bender, H. F. Jones, R. J. Rivers
Some quantum field theories described by non-Hermitian Hamiltonians are investigated. It is shown that for the case of a free fermion field theory with a mass term the Hamilt…
