Resumo(s)
New insights into transport properties of nanostructures with a linear
dispersion along one direction and a quadratic dispersion along another are
obtained by analysing their spectral stability properties under small
perturbations. Physically relevant sufficient and necessary conditions to
guarantee the existence of discrete eigenvalues are derived under rather
general assumptions on external fields. One of the most interesting features of
the analysis is the evident spectral instability of the systems in the weakly
coupled regime. The rigorous theoretical results are illustrated by numerical
experiments and predictions for physical experiments are made.
