Universal critical factor for spin-1/2 Aharonov-Bohm bound states
Vinícius Salem, Edilberto O. Silva, Fabiano M. Andrade
Whether the spin-1/2 Aharonov-Bohm Hamiltonian supports bound states has remained controversial since Hagen concluded that no such states exist for a Dirac particle. Here, we show…
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…
The Dirac equation: historical context, comparisons with the Schrödinger and Klein-Gordon equations, and elementary consequences
Thiago T. Tsutsui, Edilberto O. Silva, Antonio S. M. de Castro +1
This paper offers educational insight into the Dirac equation, examining its historical context and contrasting it with the earlier Schrödinger and Klein-Gordon (KG) equations. The…
Nonlinear refractive index changes and absorption coefficients in mesoscopic ring induced by variable effective mass
Denise Assafrao, A. G. de Lima, Edilberto O. Silva +1
This study explores the linear and nonlinear optical absorption coefficients (OAC) and refractive index changes (RIC) in quantum dot and quantum antidot systems with a position-dep…
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…
Quantum heat machines enabled by twisted geometry
Cleverson Filgueiras, Moises Rojas, Edilberto O. Silva +1
In this paper, we analyze the operation of an Otto cycle heat machine driven by a non-interacting two-dimensional electron gas on a twisted geometry. We show that due to both the e…
