We construct a one-parameter automorphism group of the injective type II1 factor with Connes spectrum {0} which is not stably conjugate to an infinite tensor product action. We construct a countable family of one-parameter automorphism groups of the injective type II1 factor such that all are stably conjugate but no two are cocycle conjugate.
