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…
Applications of the Klein-Gordon equation in the Feshbach-Villars representation in the non-inertial cosmic string space-time
Abdelmalek Bouzenada, Abdelmalek Boumali, Edilberto O. Silva
We study the relativistic quantum motion of a spineless particle using the Feshbach-Villars (FV) formalism in the spinning cosmic string spacetime. The movement equations are deriv…
Exact and approximate bound state solutions of the Schrödinger equation with a class of Kratzer-type potentials in the global monopole spacetime
Saulo S. Alves, Frankbelson dos S. Azevedo, Cleverson Filgueiras +1
This work investigates the motion of a non-relativistic charged particle within the spacetime of a global monopole. We introduce the Schrödinger equation to describe the particle's…
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…
Approximate analytical solutions of the Schrödinger equation with Hulthén potential in the global monopole spacetime
Saulo S. Alves, Márcio M. Cunha, Hassan Hassanabadi +1
In this paper, we study the nonrelativistic quantum mechanics of an electron in a spacetime containing a topological defect. We also consider that the electron is influenced by the…
