Semi-classical behavior of Pöschl-Teller coherent states

Abstract

We present a construction of semi-classical states for Pöschl-Teller potentials based on a supersymmetric quantum mechanics approach. The parameters of these "coherent" states are points in the classical phase space of these systems. They minimize a special uncertainty relation. Like standard coherent states they resolve the identity with a uniform measure. They permit to establish the correspondence (quantization) between classical and quantum quantities. Finally, their time evolution is localized on the classical phase space trajectory.

New SUSYQM coherent states for Pöschl–Teller potentials: a detailed mathematical analysis

Hervé Bergeron, Petr Siegl, A Youssef

In a recent short note (Bergeron et al 2010 Europhys. Lett. 92 60003), we have presented the good properties of a new family of semi-classical states for Pöschl–Teller potentials. These states are built from a supersymmetric quantum mechanics (SUSYQM) approach and the parameters of these 'coherent' states are points in the classical phase space. In this paper, we develop all the mathematical aspects that have been left out of the previous paper (proof of the resolution of unity, detailed calculations of the quantized version of classical observables and mathematical study of the resulting operators: problems of domains, self-adjointness or self-adjoint extensions). Some additional questions such as asymptotic behavior are also studied. Moreover, the framework is extended to a larger class of Pöschl–Teller potentials. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to 'Coherent states: mathematical and physical aspects'.

Generalized coherent states for the Pöschl-Teller potential and a classical limit

M. G. A. Crawford, Edward R. Vrscay

Coherent states in the harmonic oscillator may be defined in several equivalent ways. One definition describes coherent states as special states satisfying a minimum-uncertainty requirement in position and momentum spaces. This definition is generalized for other potentials according to a method developed by Nieto et al. [Phys. Rev. D 20, 1321 (1979)] and is herein applied to the P\"oschl-Teller potential. A classical limit based on the harmonic-oscillator coherent-state classical limit is then developed and applied to the P\"oschl-Teller minimum-uncertainty states. In this limit, classical behavior may be obtained from these quantum states. Together with a completeness argument for the generalized coherent states, this result provides insight into quantum classical correspondence through the statistical interpretation of quantum mechanics.

An Algebraic Construction of Generalized Coherent States for Shape-Invariant Potentials

Aleixo, A N F, A. B. Balantekin

Generalized coherent states for shape invariant potentials are constructed using an algebraic approach based on supersymmetric quantum mechanics. We show this generalized formalism is able to: a) supply the essential requirements necessary to establish a connection between classical and quantum formulations of a given system (continuity of labeling, resolution of unity, temporal stability, and action identity); b) reproduce results already known for shape-invariant systems, like harmonic oscillator, double anharmonic, Poschl-Teller and self-similar potentials and; c) point to a formalism that provides an unified description of the different kind of coherent states for quantum systems.

Pöschl-Teller Hamiltonian: Gazeau-Klauder type coherent states, related statistics, and geometry

Mahouton Norbert Hounkonnou, Sama Arjika, Ezinvi Baloïtcha

This work mainly addresses a construction of Gazeau-Klauder type coherent states (CSs) for a Pöschl-Teller model. Relevant characteristics are investigated. Induced geometry and statistics are studied. Then, the Berezin-Klauder-Toeplitz quantization of the classical phase space observables is presented.

New coherent states with Laguerre polynomials coefficients for the symmetric Pöschl–Teller oscillator

P Kayupe Kikodio, Zouhaı̈r Mouayn

We construct new coherent states labeled by points z of the complex plane and depending on three parameters and by replacing the coefficients of the canonical coherent states by Laguerre polynomials with an order depending on γ . These coherent states are superpositions of eigenstates of the Hamiltonian with a symmetric Pöschl–Teller potential indexed by ν , which solve an -identity operator while the resolution of the identity of the states Hilbert space is acheived at the limit We obtain their wave functions in a closed form for a special case of parameters γ and ν . We also discuss their associated coherent states transform which leads to an integral representation of Hankel type for Laguerre functions.
