Fano and Dicke effects and spin polarization in a double Rashba-ring system side coupled to a quantum wire
V. M. Apel, P. A. Orellana, M. Pacheco
The electronic transport in a system of two quantum rings side-coupled to a quantum wire is studied via a single-band tunneling tight-binding Hamiltonian. We derived analytical exp…

Transport properties of graphene nanoribbon heterostructures
L. Rosales, P. Orellana, Z. Barticevic +1
We study the electronic and transport properties of heterostructures formed by armchair graphene nanoribbons with intersections of finite length. We describe the system by a tight-…
