Bethe Ansatz in Quantum Mechanics. 2. Construction of Multi-Parameter Spectral Equations
Dieter Mayer, Alexander Ushveridze, Zbigniew Walczak
In this paper we propose a simple method for building exactly solvable multi-parameter spectral equations which in turn can be used for constructing completely integrable and exact…

Bethe Ansatz in Quantum Mechanics. 1. The Inverse Method of Separation of Variables
Dieter Mayer, Alexander Ushveridze
In this paper we formulate a general method for building completely integrable quantum systems. The method is based on the use of the so-called multi-parameter spectral equations,…

Infinite Quasi-Exactly Solvable Models
H. D. Doebner, K. Lazarow, A. G. Ushveridze
We introduce a new concept of infinite quasi-exactly solvable models which are constructable through multi-parameter deformations of known exactly solvable ones. The spectral probl…
