Scalar quasinormal and quasibound states of weakly magnetized Ernst--Schwarzschild spacetime: a confluent-Heun Wronskian approach
Danilo S. Ferreira, Luis B. Castro
We study the quasinormal-mode and quasibound-state spectra of a massless scalar field in weakly magnetized Ernst--Schwarzschild spacetime. In the separated regime, the K…
Scalar and vector bosons in a Bonnor-Melvin- spacetime: an exact Duffin-Kemmer-Petiau analysis
Francisco A. Cruz Neto, Luis B. Castro
We study scalar and vector bosons in the Bonnor--Melvin-- spacetime within the Duffin--Kemmer--Petiau (DKP) formalism. By employing Umezawa's projection operators, we separate t…
Comment on "Relativistic quantum oscillator model under the effects of the violation of Lorentz symmetry by an arbitrary fixed vector field'' by Faizuddin Ahmed
Andrés G. Jirón Vicente, Luis B. Castro, Angel E. Obispo
We obtain the correct expressions for the energy and normalized eigenfunctions for a spin-zero relativistic quantum oscillator model under the violation of Lorentz symmetry defined…
Effects of a uniform magnetic field on twisted graphene nanoribbons
Camila C. Soares, Angel E. Obispo, Andrés G. Jirón Vicente +1
In the present work, the relativistic quantum motion of massless fermions in a helicoidal graphene nanoribbon under the influence of a uniform magnetic field is investigated. Consi…
Non-radial oscillations and global stellar properties of anisotropic compact stars using realistic equations of state
Elvis J. Aquino Curi, Luis B. Castro, Cesar V. Flores +1
In this work, we have made a systematic study of how the gravitational wave frequency of the fundamental mode from compact stars is affected by anisotropic effects using realistic…
Remarks on thermodynamic properties of a double ring-shaped quantum dot at low and high temperatures
Andrés G. Jirón Vicente, Luis B. Castro, Angel E. Obispo +1
In a recent paper published in this Journal, Khordad and collaborators [J Low Temp Phys (2018) 190:200] have studied the thermodynamics properties of a GaAs double ring-shaped quan…
