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…
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…
Quantum dynamics of scalar particles in the space-time of a cosmic string in the context of gravity's rainbow
L. C. N. Santos, C. E. Mota, C. C. Barros +2
We analyze the dynamics of scalar particles in gravity's rainbow considering the space-time of a cosmic string in this modified gravity. Thus, we solve the Klein-Gordon equation fo…
Comment on "Comment on linear confinement of a scalar particle in a Gödel-type space-time"
Francisco A. Cruz Neto, Camila C. Soares, Luis B. Castro
We show that from an appropriate manipulation of the biconfluent Heun differential equation can obtain the correct expression for the energy eigenvalues for the Klein-Gordon equati…
Comment on "Effects of cosmic-string framework on the thermodynamical properties of anharmonic oscillator using the ordinary statistics and the q-deformed superstatistics approaches"
Francisco A. Cruz Neto, Luis B. Castro
We point out a misleading treatment in a recent paper published in this Journal [Eur. Phys. J. C (2018)78:106] regarding solutions for the Schrödinger equation with a anharmonic os…
