Topological Majorana States in Zigzag Chains of Plasmonic Nanoparticles

Poddubny, Alexander N; Miroshnichenko, Andrey; Slobozhanyuk, A P; Kivshar, Yuri

Description

We propose a simple realization of topological edge states in zigzag chains of plasmonic nanoparticles, mimicking the Kitaev model of Majorana fermions. We demonstrate the one-to-one correspondence between the coupled dipole equations in the zigzag plasmonic chain and the Bogoliubov-de-Gennes equations for the quantum wire on top of superconductor and support the analytical theory by the full-wave electromagnetic simulations. We reveal that localized plasmons can be excited selectively at both...[Show more]
