Potential Scattering and the Continuity of Phase-shifts
Let S(k) be the scattering matrix for a Schrödinger operator (Laplacian plus potential) on Rn with compactly supported smooth potential. It is well known that S(k) is unitary and that the spectrum of S(k) accumulates on the unit circle only at 1; moreover, S(k) depends analytically on k and therefore its eigenvalues depend analytically on k provided they stay away from 1. We give examples of sm...
متن کاملEquidistribution of phase shifts in semiclassical potential scattering
Consider a semiclassical Hamiltonian H := h2∆ + V − E where ∆ is the positive Laplacian on Rd, V ∈ C∞ 0 (Rd) and E > 0 is an energy level. We prove that under an appropriate dynamical hypothesis on the Hamilton flow corresponding to H, the eigenvalues of the scattering matrix Sh(V ) define a measure on S1 that converges to Lebesgue measure away from 1 ∈ S1 as h→ 0.

Hamiltonian hierarchy and the Hulthén potential.
We deal with the Hamiltonian hierarchy problem of the Hulthén potential within the frame of the supersymmetric quantum mechanics and find that the associated superymmetric partner potentials simulate the effect of the centrifugal barrier. Incorporating the supersymmetric solutions and using the first-order perturbation theory we obtain an expression for the energy levels of theHulthén potential...
متن کامل0 PT − symmetric form of the Hulthén potential
The fourth, missing example of an exactly solvable complex potential with PT symmetry V (x) = [V (−x)] * defined on a bent contour and leading, at the real energies, to the Jacobi polynomial wave functions is found in a generalized Hulthén interaction.
