Band gaps in the relaxed linear micromorphic continuum
A. Madeo, P. Neff, I. -D. Ghiba +2
In this note we show that the relaxed linear micromorphic model recently proposed by the authors can be suitably used to describe the presence of band-gaps in metamaterials with mi…

The NLS equation in dimension one with spatially concentrated nonlinearities: the pointlike limit
C. Cacciapuoti, D. Finco, D. Noja +1
In the present paper we study the following scaled nonlinear Schrödinger equation (NLS) in one space dimension: \[ i\frac{d}{dt} ψ^{\varepsilon}(t) =-Δψ^{\varepsilon}(t) + \frac{1}…
