Dilution Robustness for Mean Field Ferromagnets

Adriano Barra, Federico Camboni, Pierluigi Contucci

In this work we compare two different random dilution of a mean field ferromagnet: the first model is built on a Bernoulli-diluted network while the second lives on a Poisson-dilut…

Gradient theory for plasticity via homogenization of discrete dislocations

Adriana Garroni, Giovanni Leoni, Marcello Ponsiglione

In this paper, we deduce a macroscopic strain gradient theory for plasticity from a model of discrete dislocations. We restrict our analysis to the case of a cylindrical symmetry f…

2-D constrained Navier-Stokes equation and intermediate asymptotics

E. Caglioti, M. Pulvirenti, F. Rousset

We introduce a modified version of the two-dimensional Navier-Stokes equation, preserving energy and momentum of inertia, which is motivated by the occurrence of different dissipat…

Graph-like models for thin waveguides with Robin boundary conditions

C. Cacciapuoti, D. Finco

We discuss the limit of small width for the Laplacian defined on a waveguide with Robin boundary conditions. Under suitable hypothesis on the scaling of the curvature, we prove the…

Spectral Analysis of a Two Body Problem with Zero Range Perturbation

M. Correggi, G. Dell'Antonio, D. Finco

We consider a class of singular, zero-range perturbations of the Hamiltonian of a quantum system composed by a test particle and a harmonic oscillators in dimension one, two and th…

Geometric currents in piezoelectricity

Gianluca Panati, Christof Sparber, Stefan Teufel

As a simple model for piezoelectricity we consider a gas of infinitely many non-interacting electrons subject to a slowly time-dependent periodic potential. We show that in the adi…
