An amplitude-phase (Ermakov-Lewis) approach for the Jackiw-Pi model of bilayer graphene
K. V. Khmelnytskaya, H. C. Rosu
In the context of bilayer graphene we use the simple gauge model of Jackiw and Pi to construct its numerical solutions in powers of the bias potential V according to a general sche…

Genetic algorithm optimization of entanglement
Jorge C. Navarro-Munoz, H. C. Rosu, R. Lopez-Sandoval
We present an application of a genetic algorithmic computational method to the optimization of the concurrence measure of entanglement for the cases of one dimensional chains, as w…

Shape invariance through Crum transformation
Jose Orlando Organista, M. Nowakowski, H. C. Rosu
We show in a rigorous way that Crum's result on equal eigenvalue spectrum of Sturm-Liouville problems can be obtained iteratively by successive Darboux transformations. It can be s…
