Conditions for non-monotonic vortex interaction in two-band superconductors
A. Chaves, L. Komendová, M. V. Milošević +3
We describe a semi-analytic approach to the two-band Ginzburg-Landau theory, which predicts the behavior of vortices in two-band superconductors. We show that the character of the…
Wave packet dynamics and valley filter in strained graphene
Andrey Chaves, L. Covaci, Kh. Yu. Rakhimov +2
The time evolution of a wavepacket in strained graphene is studied within the tight-binding model and continuum model. The effect of an external magnetic field, as well as a strain…
Grading effects in semiconductor nanowires with longitudinal heterostructures
Andrey Chaves, J. A. K. Freire, G. A. Farias
The role of graded interfaces between materials in a cylindrical free-standing quantum wire with longitudinal heterostructures is theoretically investigated, by solving the Schrödi…
Dynamical gap generation in graphene nanoribbons: An effective relativistic field theoretical model
A. J. Chaves, G. D. Lima, W. de Paula +4
We show that the assumption of a nontrivial zero band gap for a graphene sheet within an effective relativistic field theoretical model description of interacting Dirac electrons o…
