Disordered Fermions on lattices and their spectral properties
SD Barreto, F Fidaleo - Journal of Statistical Physics, 2011 - Springer
We study Fermionic systems on a lattice with random interactions through their dynamics
and the associated KMS states. These systems require a more complex approach compared …

On the structure of KMS states of disordered systems
SD Barreto, F Fidaleo - Communications in mathematical physics, 2004 - Springer
We study the set of KMS states of spin systems with random interactions. This is done in the
framework of operator algebras by investigating Connes and Borchers Γ–invariants of W …

KMS states and the chemical potential for disordered systems
F Fidaleo - Communications in mathematical physics, 2006 - Springer
We extend the theory of the chemical potential associated to a compact separable gauge
group, to the case of disordered quantum systems. This is done in the framework of operator …

Some topics in quantum disordered systems
SD Barreto, F Fidaleo - arXiv preprint math/0501121, 2005 - arxiv.org
We discuss some recent results connected with the properties of temperature states of
quantum disordered systems. This analysis falls within the natural framework of operator …
