Effects of curvature on the electronic states of a two-dimensional mesoscopic ring
Luís Fernando C. Pereira, Fabiano M. Andrade, Cleverson Filgueiras +1
The effects of surface curvature on the motion of electrons in a mesoscopic two-dimensional ring on a cone in the presence of external magnetic fields are examined. The approach fo…
Self-adjoint extension approach for singular Hamiltonians in (2+1) dimensions
Vinicius Salem, Ramon F. Costa, Edilberto O. Silva +1
In this work, we review two methods used to approach singular Hamiltonians in (2+1) dimensions. Both methods are based on the self-adjoint extension approach. It is very common to…
Narrow peaks of full transmission in simple quantum graphs
A. Drinko, F. M. Andrade, D. Bazeia
This work deals with quantum graphs, focusing on the transmission properties they engender. We first select two simple diamond graphs, and two hexagonal graphs in which the vertice…
Modifications of electron states, magnetization and persistent current in a quantum dot by controlled curvature
Luis Fernando C. Pereira, Fabiano M. Andrade, Cleverson Filgueiras +1
In this work, we use the thin-layer quantization procedure to study the physical implications due to curvature effects on a quantum dot in the presence of an external magnetic fiel…
Simple quantum graphs proposal for quantum devices
A. Drinko, F. M. Andrade, D. Bazeia
The control of the quantum transport is an issue of current interest for the construction of new devices. In this work, we investigate this possibility in the realm of quantum grap…
Basin entropy behavior in a cyclic model of the rock-paper-scissors type
M. Mugnaine, F. M. Andrade, J. D. Szezech +1
We deal with stochastic network simulations in a model with three distinct species that compete under cyclic rules which are similar to the rules of the popular rock-paper-scissors…
