Extended Scalar Particle Solutions in Black String Spacetimes with Anisotropic Quintessence

M. L. Deglmann, B. V. Simão, B. V. Simão +1

We present novel solutions to the Klein-Gordon equation in a black string spacetime immersed in an anisotropic quintessence fluid and surrounded by a cloud of strings (BCK spacetim…

Curvature Corrections to the Yukawa Potential in Tolman Metrics

J. V. Zamperlini, C. C. Barros

This work investigates curvature-induced modifications to the Yukawa potential in static, spherically symmetric spacetimes described by Tolman metrics, focusing on their implicatio…

Emergence of Dark Phases in Scalar Particles within the Schwarzschild-Kiselev-Letelier Spacetime

B. V. Simão, M. L. Deglmann, C. C. Barros

This work focuses on the emergence of dark phases (dark energy-induced phases) in the radial wave function of scalar particles. We achieve this by presenting novel solutions to the…

Kiselev black strings: the charged rotating solutions

Leonardo G. Barbosa, Victor Hugo M. Ramos, Luis Cesar N. dos Santos +1

We investigate the properties of a charged rotating black string immersed in a Kiselev anisotropic fluid in anti-de Sitter (AdS) spacetime. The Einstein-Maxwell equations with an a…

Scalar bosons in Bonnor-Melvin- universe: Exact solution, Landau levels and Coulomb-like potential

L. G. Barbosa, C. C. Barros

In this work, we study spin-0 particles in a spacetime whose structure is determined by a homogeneous magnetic field and a cosmological constant. For this purpose, we take into acc…
