Abstract

In this article we show that the quasi-free flows on the Cuntz algebra O2\mathcal{O}_2 are generically classifiable by the inverse temperature of their unique KMS state. Along the way, we show that a large class of quasi-free flows on the Cuntz algebra On\mathcal{O}_n are generically equivariantly Z\mathcal{Z}-stable and their corresponding dual action has the Rokhlin property generically.
