Families of type III KMS states on a class of C * -algebras containing O n and Q N
We construct a family of purely infinite C *-algebras, Qλ for λ ∈ (0, 1) that are classified by their K-groups. There is an action of the circle T with a unique KMS state ψ on each Qλ. For λ = 1/n, Q1/n≅On, with its usual T action and KMS state.
