Equivalence of q-bosons using the exponential phase operator
S. U. Park
Abstract
Various forms of the q-boson are explained and their hidden symmetry revealed by transformations using the exponential phase operator. Both the one-component and the multicomponent q-bosons are discussed. As a byproduct, we obtain a new boson algebra having a shifted vacuum structure and define a global operatal U(1) gauge transformation.
