### Ensemble nonequivalence in random graphs with modular structure

- Mathematics
- 2016

Breaking of equivalence between the microcanonical ensemble and the canonical ensemble, describing a large system subject to hard and soft constraints, respectively, was recently shown to occur in…

### Ensemble inequivalence and absence of quasi-stationary states in long-range random networks

- Physics
- 2016

Ensemble inequivalence has been previously displayed only for long-range interacting systems with non-extensive energy. In order to perform the thermodynamic limit, such systems require an…

### Ensemble equivalence in spin systems with short-range interactions

- Physics
- 2011

We study the problem of ensemble equivalence in spin systems with short-range interactions under the existence of a first-order phase transition. The spherical model with nonlinear nearest-neighbour…

### Complete analysis of ensemble inequivalence in the Blume-Emery-Griffiths model.

- PhysicsPhysical review. E
- 2017

Ergodicity breaking is discussed, which is highlighted by the presence of gaps in the accessible values of magnetization at low energies: it also displays new interesting patterns that are not present in the Blume-Capel model.

### Metastability and discrete spectrum of long-range systems

- PhysicsProceedings of the National Academy of Sciences
- 2021

The spectrum of systems with power-law decaying couplings remains discrete up to the thermodynamic limit, showing that several traditional results on the chaotic nature of the spectrum in many-body quantum systems are not satisfied in the presence of long-range interactions.

### Statistical mechanics: contributions to rigidity percolation and long range interacting systems

- Physics
- 2011

The statistical mechanics of long range interacting systems was already the subject of my PhD thesis, done under the joint supervision of Thierry Dauxois and Stefano Ruffo, but research on the subject has followed new directions since 2003.

### The ambiguity of nestedness under soft and hard constraints

- Computer ScienceScientific reports
- 2020

This work proposes a clarification that exploits the recent finding that random networks where the degrees are enforced as hard constraints (microcanonical ensembles) are thermodynamically different from random networksWhere the degrees is enforced as soft constraints (canonicalEnsembles), and disentangles distinct notions of nestedness captured by different metrics.

### fastball: A fast algorithm to sample bipartite graphs with fixed degree sequences

- Computer Science, Mathematics
- 2021

It is shown that fastball randomly samples large bipartite graphs with ﬁxed degrees more than four times faster than curveball, and the value of this faster algorithm in the context of the ﬂxed degree sequence model for backbone extraction is illustrated.

### Comparing alternatives to the fixed degree sequence model for extracting the backbone of bipartite projections

- Computer ScienceScientific reports
- 2021

Four potential alternatives to the fixed degree sequence model (FDSM) are explored and it is found that the computationally-fast SDSM offers a statistically conservative but close approximation of the Computationally-impractical FDSM under a wide range of conditions, and that it correctly recovers a known community structure even when the signal is weak.

### Inequivalence of ensembles in a system with long-range interactions.

- PhysicsPhysical review letters
- 2001

The global phase diagram of the infinite-range Blume-Emery-Griffiths model is studied both in the canonical and in the microcanonical ensembles to find that below the tricritical point, when the canonical transition is first order, the phase diagrams of the two ensemble disagree.

### The cavity method for large deviations

- Computer Science
- 2005

The approach, based on an extension of the cavity method to atypical realizations of the quenched disorder, allows us to compute exponentially small probabilities (rate functions) over different classes of random graphs.

- Mathematics

We show that large deviation properties of Erdös-Rényi random graphs can be derived from the free energy of the q-state Potts model of statistical mechanics. More precisely the Legendre transform of…

Using the theory of large deviations, we analyze the phase transition structure of the Curie–Weiss–Potts spin model, which is a mean-field approximation to the nearest-neighbor Potts model. It is…

Abstract:So far the problem of a spin glass on a Bethe lattice has been solved only at the replica symmetric level, which is wrong in the spin glass phase. Because of some technical difficulties,…

We investigate numerically and analytically Potts models on `thin' random graphs - generic Feynman diagrams, using the idea that such models may be expressed as the limit of a matrix model. The thin…
