Supercritical phase transition on the Toeplitz algebra of
Marcelo Laca, Tyler Schulz
We study the high-temperature equilibrium for the C*-algebra recently considered by an Huef, Laca and Raeburn. We show that the si…
On Toeplitz algebras of product systems
Elias G. Katsoulis, Marcelo Laca, Camila F. Sehnem
In the setting of product systems over group-embeddable monoids, we consider nuclearity of the associated Toeplitz C*-algebra in relation to nuclearity of the coefficient algebra.…
Crystallization of C*-algebras
Marcelo Laca, Sergey Neshveyev, Makoto Yamashita
Given a C-algebra with an almost periodic time evolution , we define a new C-algebra , which we call the crystal of , that represents the zero temperatur…
Relative topological principality and the ideal intersection property for groupoid C*-algebras
Chris J. Eagle, Gavin Goerke, Marcelo Laca
We introduce the notion of relative topological principality for a family of open subgroupoids of a Hausdorff étale groupoid . The C*-algebras of the grou…
Quantum Statistical Mechanics via Boundary Conditions. A Groupoid Approach to Quantum Spin Systems
Lucas Affonso, Rodrigo Bissacot, Marcelo Laca
We use a groupoid model for the spin algebra to introduce boundary conditions on quantum spin systems via a Poisson point process representation. We can describe KMS states of quan…
KMS states of quasi-free dynamics on -algebras of product systems over right LCM monoids
Luca Eva Gazdag, Marcelo Laca, Nadia S. Larsen
We generalise recent results of Afsar, Larsen and Neshveyev for product systems over quasi-lattice orders by showing that the equilibrium states of quasi-free dynamics on the Nica-…
