Diverging eigenvalues in domain truncations of Schrödinger operators with complex potentials
Iveta Semorádová, Petr Siegl
Diverging eigenvalues in domain truncations of Schrödinger operators with complex potentials are analyzed and their asymptotic formulas are obtained. Our approach also yields asymp…
Log-anharmonic oscillator and its large-N solution
Miloslav Znojil, Iveta Semorádová
The large-N expansion technique is tested via an anomalous, soft-core potential which admits the tunneling through its central barrier. The precision of the approximation is found…
Crypto-Hermitian Approach to the Klein-Gordon Equation
Iveta Semorádová
We explore the Klein-Gordon equation in the framework of crypto-Hermitian quantum mechanics. Solutions to common problems with probability interpretation and indefinite inner produ…
Quantum square well with logarithmic central spike
Miloslav Znojil, Iveta Semorádová
Linear square-well Schrödinger equation endowed with a singular logarithmic spike in the origin is studied. The study is methodical, motivated by the problem of non-gausson states…
The problem of coexistence of several non-Hermitian observables in PT-symmetric quantum mechanics
Miloslav Znojil, Iveta Semorádová, František Rŭžička +2
During the recent developments of quantum theory it has been clarified that the observable quantities (like energy or position) may be represented by operators (with real spectra)…
