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…
Anisotropic Compact Stars in Rastall-Rainbow Gravity
Clésio E. Mota, Luis C. N. Santos, Franciele M. da Silva +3
In this work, we have investigated anisotropic neutron stars in the framework of Rastall-Rainbow gravity. All our calculations were computed using the IU-FSU realistic equation of…
Combined Rastall and Rainbow theories of gravity with applications to neutron stars
Clésio E. Mota, Luis C. N. Santos, Guilherme Grams +2
The possibility of modifications on general relativity is investigated. We propose an alternative theory of gravity constructed with the combination of Rastall and Rainbow theories…
Klein-Gordon oscillator in a topologically nontrivial space-time
L. C. N. Santos, C. E. Mota, C. C. Barros
In this study, we analyze solutions of the wave equation for scalar particles in a space-time with nontrivial topology. Solutions for the Klein--Gordon oscillator are found conside…
Can generalized TOV equations explain neutron star macroscopic properties?
Clésio E. Mota, Guilherme Grams, Débora P. Menezes
In the quest for describing massive neutron stars with radii compatible with recent expectations, we take a different approach in the present paper and, instead of tuning the equat…
