چکیده
Within the framework of Lanczos-inspired perturbation theory wave functions and energies in the short-range potential V (x) = a ρ 2 (x) + λ ρ 4 (x) with ρ(x) = sech αx and a small coupling λ are shown obtainable in closed form.

Wronskian and Casorati determinant representations for Darboux-Pöschl-Teller potentials and their difference extensions
We consider some special reductions of generic Darboux-Crum dressing formulas and of their difference versions. As a matter of fact we obtain some new formulas for Darboux-Pöschl-Teller potentials, their difference deformations and the related eigenfunctions.
متن کاملAharonov-Bohm effect on AdS2 and nonlinear supersymmetry of reflectionless Pöschl-Teller system
The origin and nature of a special nonlinear supersymmetry of a reflectionless Pöschl-Teller system are explained by the Aharonov-Bohm effect for a nonrelativistic particle on AdS2. A key role in supersymmetric structure appearing after reduction by a compact generator of the AdS2 isometry is shown to be played by discrete symmetries related to space and time reflections in the ambient Minkowsk...
متن کاملPeculiarities of the hidden nonlinear supersymmetry of Pöschl-Teller system in the light of Lamé equation
A hidden nonlinear bosonized supersymmetry was revealed recently in Pöschl-Teller and finite-gap Lamé systems. In spite of the intimate relationship between the two quantum models, the hidden supersymmetry in them displays essential differences. In particular, the kernel of the supercharges of the Pöschl-Teller system, unlike the case of Lamé equation, includes nonphysical states. By means of L...
متن کاملCoherent states of Pöschl-Teller potential and their revival dynamics
A recently developed algebraic approach for constructing coherent states for solvable potentials is used to obtain the displacement operator coherent state of the Pöschl-Teller potential. We establish the connection between this and the annihilation operator coherent state and compare their properties. We study the details of the revival structure arising from different time scales underlying t...
متن کاملInformation-theoretic measures for Morse and Pöschl–Teller potentials
The spreading of the quantum-mechanical probability cloud for the ground state of the Morse and modified Pöschl–Teller potentials, which controls the chemical and physical properties of some molecular systems, is studied in position and momentum space by means of global (Shannon’s information entropy, variance) and local (Fisher’s information) informationtheoretic measures. We establish a gener...
