Metallic-insulator phase transitions in the extended Harper model
João Chakrian, Marcelo L. Lyra, Jonas R. F. Lima
In this work we investigate the transport properties of non-relativistic quantum particles on incommensurate multilayered structures with the thicknesses of the layers follow…
Interface and electromagnetic effects in the valley splitting of Si quantum dots
Jonas R. F. Lima, Guido Burkard
The performance and scalability of silicon spin qubits depend directly on the value of the conduction band valley splitting. In this work, we investigate the influence of electroma…
Wave transmission and its universal fluctuations in one-dimensional systems with Lévy-like disorder: Schrödinger, Klein-Gordon and Dirac equations
Anderson L. R. Barbosa, Jonas R. F. Lima, Luiz Felipe C. Pereira
We investigate the propagation of waves in one-dimensional systems with Lévy-type disorder. We perform a complete analysis of non-relativistic and relativistic wave transmission su…
Magnetic and geometric effects on the electronic transport of metallic nanotubes
Felipe Serafim, Fernando A. N. Santos, Jonas R. F. Lima +3
The investigation of curved low-dimensional systems is a topic of great research interest. Such investigations include two-dimensional systems with cylindrical symmetry. In this wo…
Electronic, magnetic and optical properties of penta-BN nanoribbons: a first principles study
M. A. L. Dantas, N. F. Frazão, David L. Azevedo +1
The search for new materials is a very intense task in many technological areas. In 2015, a new variant of graphene was proposed, the pentagraphene, which was followed by the propo…
Electronic, optical, vibrational and thermodynamic properties of phaBN structure: a first principles study
J. M. Pontes, N. F. Frazão, David L. Azevedo +1
In 2015, a new two dimensional (2D) carbon allotrope, called phagraphene, was theoretically proposed. Based on this structure, we propose here a new boron nitride structure called…
