Model of collision-induced constructive quantum interference

Institute of Physics, Nicolaus Copernicus University, Grudziądzka 5/7, 87-100 Toruń, Poland

Abstract

Yang and collaborators reported recently observation of unexpected resonaces in so-called hybrid excitation spectra of sodium vapour. Yang and Xie presented a theoretical model in which the resonances were interpreted as in terms of collision constructive quantum interference effects. This work reports results of testing of the applicability range of the model and demonstrates its serious limitations.
