Inhomogeneous Superconductivity in Comb-Shaped Josephson Junction Networks
P. Sodano, A. Trombettoni, P. Silvestrini +2
We show that some of the Josephson couplings of junctions arranged to form an inhomogeneous network undergo a non-perturbative renormalization provided that the network's connectiv…

Topological Filters for Solitons in Coupled Waveguides Networks
R. Burioni, D. Cassi, P. Sodano +2
We study the propagation of discrete solitons on chains of coupled optical waveguides where finite networks of waveguides are inserted at some points. By properly selecting the top…
