چکیده
The intertwining operator technique is applied to difference Schrödinger equations with operator-valued coefficients. It is shown that these equations appear naturally when a discrete basis is used for solving a multichannel Schrödinger equation. New families of exactly solvable multichannel Hamiltonians are found.

The concept of energy-dependent forces in quantum mechanics is re-analysed. We suggest a simplification of their study via the representation of each self-adjoint and energy-dependent Hamiltonian H = H(E) with real spectrum by an auxiliary non-Hermitian operator K which remains energy-independent. Practical merits of such an approach to the Schrödinger equations with energy-dependent potentials...

The effect of rule (4) on a series or parallel sequence of quantum mechanical steps is to insure that a conscious observer does not skip a step. This rule effectively places the observer in continuous contact with the system.

The higher order susy partners of Schrödinger Hamiltonians can be explicitly constructed by iterating a nonlinear difference algorithm coinciding with the Bäcklund superposition principle used in soliton theory. As an example, it is applied in the construction of new higher order susy partners of the free particle potential, which can be used as a handy tool in soliton theory. Recent studies co...
