Abstract
In this work, we construct different classes of coherent states related to a quantum system, recently studied in [1], of an electron moving in a plane in uniform external magnetic and electric fields which possesses both discrete and continuous spectra. The eigenfunctions are realized as an orthonormal basis of a suitable Hilbert space appropriate for building the related coherent states. These latter are achieved in the context where we consider both spectra purely discrete obeying the criteria that a family of coherent states must satisfy.
Highlights
From a generalization of the definition of canonical coherent states, Gazeau and Klauder proposed a method to construct temporally stable coherent states for a quantum system with one degree of freedom [2]
In some previous works, motivated by these developments, multidimensional vector coherent states have been performed for Hamiltonians describing the nanoparticle dynamics in terms of a system of interacting bosons and fermions [6]; from a matrix formulation of the Landau problem and the corresponding Hilbert space, an analysis of various multi-matrix vector coherent states extended to diagonal matrix domains has been performed on the basis of Landau levels [7]
The motion of an electron in a noncommutative (x, y) plane, in a constant magnetic field background coupled with a harmonic potential has been examined with the relevant vector coherent states constructed and discussed [8]
Summary
From a generalization of the definition of canonical coherent states, Gazeau and Klauder proposed a method to construct temporally stable coherent states for a quantum system with one degree of freedom [2]. Following the method developed in [2, 4], we investigate in a recent work [1] by considering Landau levels, various classes of coherent states as in [9, 5, 10] arising from physical. The present paper is a direct continuation of our work in reference [1], where we construct different classes of coherent states corresponding to the case of discrete spectrum.
