Назив: | About a new family of coherent states for some SU(1,1) central field potentials | Аутори: | Popov D. Sajfert V. Pop N. Chiritoiu V. |
Датум издавања: | 6-мар-2013 | Часопис: | Journal of Mathematical Physics | Сажетак: | In this paper, we shall define a new family of coherent states which we shall call the "mother coherent states," bearing in mind the fact that these states are independent from any parameter (the Bargmann index, the rotational quantum number J, and so on). So, these coherent states are defined on the whole Hilbert space of the Fock basis vectors. The defined coherent states are of the Barut-Girardello kind, i.e., they are the eigenstates of the lowering operator. For these coherent states we shall calculate the expectation values of different quantum observables, the corresponding Mandel parameter, the Husimi's distribution function and also the P- function. Finally, we shall particularize the obtained results for the three-dimensional harmonic and pseudoharmonic oscillators. © 2013 American Institute of Physics. | URI: | https://open.uns.ac.rs/handle/123456789/9074 | ISSN: | 00222488 | DOI: | 10.1063/1.4795137 |
