We show that with respect to the Haar state, the joint distributions of the generators
of Van Daele and Wang’s free orthogonal quantum groups are modeled by free
families of generalized circular elements and semicircular elements in the large
(quantum) dimension limit. We also show that this class of quantum groups acts
naturally as distributional symmetries of almost-periodic free Araki–Woods
factors.
