In this thesis, we develop the methodology for exploring the electronic and optical
properties of an artificial benzene ring, both analytically as well as numerically
through direct diagonalization using the configuration interaction method. We
use the extended Hubbard Hamiltonian to model the interactions with different
numbers of electrons, with spin projection and total spin resolved as good quantum
numbers. The focus in this work is on the charged case and the emergence of an
artificial gauge field and how it can be detected optically. We also examine three
other cases of the artificial benzene ring, the single electron case, the charge neutral
or half filled case, and the quarter filled case. Ground state properties, excited
state spectra, and interactions with light are described.
