Symbolic-manipulation constructions of Hilbert-space metrics in quantum mechanics
arXiv:1105.4525
Abstract
The problem of the determination of the Hilbert-space metric which renders a given Hamiltonian self-adjoint is addressed from the point of view of applicability of computer-assisted algebraic manipulations. An exactly solvable example of the so called Gegenbauerian quantum-lattice oscillator is recalled for the purpose. Both the construction of suitable metric (basically, the solution of the Dieudonne's operator equation) and the determination of its domain of positivity are shown facilitated by the symbolic algebraic manipulations and by MAPLE-supported numerics and graphics.
