Classification of the conditionally observable spectra exhibiting central symmetry
arXiv:0711.3947 · doi:10.1016/j.physleta.2007.11.015
Abstract
We show how in PT-symmetric 2J-level quantum systems the assumption of an upside-down symmetry (or duality) of their spectra simplifies their classification based on the non-equivalent pairwise mergers of the energy levels.
