Number-phase entropic uncertainty relations and Wigner functions for solvable quantum systems with discrete spectra
Full text linkIn this letter, the number-phase entropic uncertainty relation and the
number-phase Wigner function of generalized coherent states associated to a few
solvable quantum systems with nondegenerate spectra are studied. We also
investigate time evolution of number-phase entropic uncertainty and Wigner
function of the considered physical systems with the help of temporally stable
Gazeau-Klauder coherent states.Comment: 10 pages, 9 figures; To appear in Phys Lett A 200
Quantum phase properties associated to solvable quantum systems using the nonlinear coherent states approach
Full text linkIn this paper we study the quantum phase properties of {\it "nonlinear
coherent states"} and {\it "solvable quantum systems with discrete spectra"}
using the Pegg-Barnett formalism in a unified approach. The presented procedure
will then be applied to few special solvable quantum systems with known
discrete spectrum as well as to some new classes of nonlinear oscillators with
particular nonlinearity functions. Finally the associated phase distributions
and their nonclasscial properties such as the squeezing in number and phase
operators have been investigated, numerically.Comment: 11 pages, 12 figure
