Supercritical phase transition on the Toeplitz algebra of ${\mathbb N^\times}\ltimes \mathbb{Z}$

We study the high-temperature equilibrium for the \mathrm{C}^{*} -algebra \mathcal{T}({\mathbb{N^}\times}\ltimes \mathbb{Z}) recently considered by an Huef, Laca, and Raeburn. We show that the simplex of \mathrm{KMS}_{\beta} states at each inverse temperature \beta in the critica...
