Statistical mechanics and dynamics of solvable models with long-range interactions
For systems with long-range interactions, the two-body potential decays at large distances
as V (r)∼ 1/rα, with α≤ d, where d is the space dimension. Examples are: gravitational …

Strongly correlated flat-band systems: The route from Heisenberg spins to Hubbard electrons
On a large class of lattices (such as the sawtooth chain, the kagome and the pyrochlore
lattices), the quantum Heisenberg and the repulsive Hubbard models may host a completely …

Comparing alternatives to the fixed degree sequence model for extracting the backbone of bipartite projections
Projections of bipartite or two-mode networks capture co-occurrences, and are used in
diverse fields (eg, ecology, economics, bibliometrics, politics) to represent unipartite …

Complete analysis of ensemble inequivalence in the Blume-Emery-Griffiths model
We study inequivalence of canonical and microcanonical ensembles in the mean-field
