Phase shift operator and cyclic evolution in finite dimensional Hilbert space | | Ramandeep S. Johal
; | | Date: |
24 Mar 2000 | | Subject: | quant-ph | | Abstract: | We address the problem of phase shift operator acting as time evolution operator in Pegg-Barnett formalism. It is argued that standard shift operator is inconsistent with the behaviour of the state vector under cyclic evolution. We consider a generally deformed oscillator algebra at q-root of unity, as it yields the same Pegg-Barnett operator and show that shift operator meets our requirement. | | Source: | arXiv, quant-ph/0003114 | | Services: | Forum | Review | PDF | Favorites | |
