Abstract

We present methods to construct flows with varying set of KMS_∞ states on a given simple unital AF-algebra. It follows, for example, that for any pair D₊ and D₋ of non-empty compact metric spaces there is a flow σ = ( σ t ) t ∈ R on the CAR algebra whose set of KMS_∞ states is homeomorphic to D₊ while the set of KMS_∞ states for the inverted flow ( σ − t ) t ∈ R is homeomorphic to D₋. Remarkably the flows that realize all such pairs D_± can be chosen to have isomorphic KMS bundles.
