We analyze the role of the Allee effect, a positive correlation between population density and mean individual fitness, for ecological communities formed by a large number of species. Our study is performed using the generalized Lotka-Volterra model

The random Lotka-Volterra model is widely used to describe the dynamical and thermodynamic features of ecological communities. In this work, we consider random symmetric interactions between species and analyze the strongly competitive interaction ca

In this letter we study a reference model in theoretical ecology, the disordered Lotka-Volterra model for ecological communities, in the presence of finite demographic noise. Our theoretical analysis, which takes advantage of a mapping to an equilibr

Dynamical Mean-Field Theory (DMFT) replaces the many-body dynamical problem with one for a single degree of freedom in a thermal bath whose features are determined self-consistently. By focusing on models with soft disordered $p$-spin interactions, w

The response of amorphous solids to an applied shear deformation is an important problem, both in fundamental and applied research. To tackle this problem, we focus on a system of hard spheres in infinite dimensions as a solvable model for colloidal

The origin of the glass transition is one of the most debated, open problems both in experimental and theoretical physics. Already in the nineties the Nobel Prize winner P. W. Anderson asserted that the deepest and most interesting unsolved problem i

In Chap. 2 we presented a rather broad overview of renowned theories about the glass transition. In the last decades, the study of glasses at low temperature has also attracted significant interest, both from a theoretical and an experimental point o

This chapter aims to emphasize the connections between the spherical perceptron and generic sphere models, subject either to hard-core or to a soft potential. The following chapter is structured in two parts. In the first part, we present results alr

This chapter attempts to develop a systematic perturbative formalism around the Bethe solution. The results presented here are the object of a recent paper [3] with collaborators from the Universities of Rome and Turin. This work was motivated by lon
