Abstract

An infinitely deep square-well potential is studied by an SU(1,1) algebra, not by an SO(2) algebra. The creation and annihilation operators for the system are obtained from the factorization method. Closed analytical expressions for the matrix elements of some relevant functions are evaluated.

The Wigner Function for a Quantum System with an Infinitely Deep Square-Well Potential

Shi‐Hai Dong, Guo-Hua Sun, Yu Jiang

The Wigner distribution function for a quantum system with an infinitely deep square-well potential is obtained analytically and presented by plotting the Wigner distribution functions on the quantum phase space. The cross-matrix elements of the expectation values of some classical quantities are also obtained. The case of the symmetrical square-well potential is studied briefly.

THE HIDDEN SYMMETRY FOR A QUANTUM SYSTEM WITH A PÖSCHL–TELLER-LIKE POTENTIAL

Shi‐Hai Dong, Guo-Hua Sun, Yu Tang

The eigenvalues and eigenfunctions of the Schrödinger equation with a Pöschl–Teller (PT)-like potential are presented. A realization of the creation and annihilation operators for the wave functions is carried out. It is shown that these operators satisfy the commutation relations of an SU(1,1) group. Closed analytical expressions are evaluated for the matrix elements of different functions, sin (ρ) and [Formula: see text] with ρ=πx/L.

Square-well potential by an algebraic approach

Sabre Kais, Raphael David Levine

The spectrum-generating algebra for the problem of a particle in a potential well is shown to be su(1,1). Both the infinitely deep and finite square wells are considered. The generators can also be derived via a systematic procedure for determining the time-dependent constants of the motion. The coherent states are explicitly constructed.

A realization of the dynamical group for the square-well potential and its coherent states

R. Lemus, Alejandro Frank

A realization of the ladder operators for the infinitely deep well potential is presented. Both the asymmetric and symmetric wells are discussed. It is shown that these operators satisfy the commutation relations for the SU (1, 1) group. Closed analytical expressions for the matrix elements of some relevant functions are obtained. Perelomov coherent states for this system are explicitly constructed. The behaviour of the dispersion relation and the time evolution for such states are examined.

Coherent states for one-dimensional infinitely deep square potential well

NI Zhi-xiang

The energy spectrum-generating algebra for one-dimensional infinitely deep square potential well is constructed by using an additional phase variable, and a class of sets of the annihilation-operator coherent states are introduced. These sets are strongly continuous in their parameter on the whole complex plane and satisfy the overcompleteness relation in a curved parameter space with rotational symmetry.
