Finite element 3-D model of a double quantum ring: effects of electric and laser fields on the interband transition
Adrian Radu, Cristina Stan, Doina Bejan
In this work, the changes in the energy of electrons and holes, oscillator strength and interband transition time when external fields are applied to a GaAs/AlGaAs semiconductor do…

Ballistic 3-port interferometric logic gates in the quantum Hall regime
A. Radu, S. Iftimie, D. Dragoman
We show that a 3-port interferometer, defined by quantum point contacts in a two-dimensional electron gas, and working in the quantum Hall regime, can implement different logic gat…

Optical analogues of quantum chirality
Daniela Dragoman, Adrian Radu, Sorina Iftimie
We show that the quantum chirality of charge carriers in graphene can be mimicked in optical structures. More precisely, we demonstrate that the particular form of the transmission…
