C. Quesne, Completeness of photon-added squeezed vacuum and one-photon states and of photon-added coherent states on a circle, PHYS LETT A, 288(5-6), 2001, pp. 241-250
A discrete completeness relation and a continuous one with a positive measu
re are found for the photon-added squeezed vacuum states. Extension to the
photon-added squeezed one-photon states is considered. Photon-added coheren
t states on a circle are introduced. Their normalization and unity resoluti
on relation are given. (C) 2001 Elsevier Science B.V. All rights reserved.
