The Hilbert-Space Structure of Non-Hermitian Theories with Real Spectra
R. Kretschmer, L. Szymanowski
We investigate the quantum-mechanical interpretation of models with non-Hermitian Hamiltonians and real spectra. After describing a general framework to reformulate such models in…
Quasi-Hermiticity in infinite-dimensional Hilbert spaces
R. Kretschmer, L. Szymanowski
In infinite-dimensional Hilbert spaces, the application of the concept of quasi-Hermiticity to the description of non-Hermitian Hamiltonians with real spectra may lead to problems…
The Interpretation of Quantum-Mechanical Models with Non-Hermitian Hamiltonians and Real Spectra
R. Kretschmer, L. Szymanowski
We study the quantum-mechanical interpretation of models with non-Hermitian Hamiltonians and real spectra. We set up a general framework for the analysis of such systems in terms o…
Multi-channel Bethe-Salpeter equation
J. Boguszynski, H. D. Dahmen, R. Kretschmer +1
A general form of multi-channel Bethe-Salpeter equation is considered. In contradistinction to the hitherto applied approaches, our coupled system of equations leads to the simulta…
Collinear Asymptotic Dynamics for Massive Particles. Multi-Channel Regge Behaviour
J. Boguszynski, H. D. Dahmen, R. Kretschmer +1
The high-energy behaviour in a multi-channel system is investigated in the framework of collinear asymptotic dynamics for massive particles. We consider the most general trilinear…
Collinear Asymptotic Dynamics for Massive Particles. Reggeization and Eikonalization
J. Boguszynski, H. D. Dahmen, R. Kretschmer +3
The dynamics of massive particles in the collinear high momentum regime is investigated. Methods hitherto exploiting large time asymptotic Hamiltonians in the Dirac picture for the…
