Impact of the Sagnac Effect on Thermodynamic and Magnetocaloric Properties of a Rotating Two-Dimensional Electron Gas
Cleverson Filgueiras, Moises Rojas, Vinicius T. Pieve +1
This work investigates the impact of the Sagnac effect on the thermodynamic properties of a non-interacting two-dimensional electron gas (2DEG) in a rotating sample under the influ…
Study on the effects of anisotropic effective mass on electronic properties, magnetization and persistent current in semiconductor quantum ring with conical geometry
Francisco A. G. de Lira, Luís Fernando C. Pereira, Edilberto O. Silva
We study a 2D mesoscopic ring with an anisotropic effective mass considering surface quantum confinement effects. Consider that the ring is defined on the surface of a cone, which…
Optical and electronic properties of a two-dimensional quantum ring under rotating effects
Daniel F. Lima, Frankbelson dos S. Azevedo, Luís Fernando C. Pereira +2
This work presents a study on the nonrelativistic quantum motion of a charged particle in a rotating frame, considering the Aharonov-Bohm effect and a uniform magnetic field. We de…
Modification of Landau levels in a two-dimensional ring due to rotation effects and edge states
Luís Fernando C. Pereira, Edilberto O. Silva
We investigate the properties of a two-dimensional quantum ring under rotating and external magnetic field effects. We initially analyse the Landau levels and inertial effects on t…

Francisco A. G. de Lira, Edilberto O. Silva
An alternative model to describe the electronic and thermal properties of quantum dot based on triangle geometry is proposed. The model predicts characteristics and limitations of…
Study of electronic properties, Magnetization and persistent currents in a mesoscopic ring by controlled curvature
Luís Fernando C. Pereira, Fabiano M. Andrade, Cleverson Filgueiras +1
We study the model of a noninteracting spinless electron gas confined to the two-dimensional localized surface of a cone in the presence of external magnetic fields. The localized…

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…
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…
Curved non-interacting two-dimensional electron gas with anisotropic mass
Pedro H. Souza, Edilberto O. Silva, Moises Rojas +1
In the da Costa's thin-layer approach, a quantum particle moving in a 3D sample is confined on a curved thin interface. At the end, the interface effects are ignored and such quant…
Influence of a Pseudo Aharonov-Bohm field on the quantum Hall effect in Graphene
Cleverson Filgueiras, Rosinildo Fidelis, Diego Cogollo +1
The effect of an Aharonov-Bohm (AB) pseudo magnetic field on a two dimensional electron gas in graphene is investigated. We consider it modeled as in the usual AB effect but since…
