We investigate the quantum evolution of the universe in the presence of two types of dark
energies. First, we consider the phantom class (ω<− 1) which would be responsible for a …

We investigate the Casimir effect of the massless scalar field in a cavity formed by ideal
parallel plates in the spacetime generated by a rotating axially symmetric distribution of …

Neste trabalho, realizamos um estudo das equações de Klein-Gordon e de Dirac no espaço-
tempo de Bonnor-Melvin com constante cosmológica. Obtivemos o espectro de energia em …

We calculate thermal corrections to the Casimir energy of a massless scalar field in the Kerr
black hole surrounded by quintessence, taking into account the metrics derived by Ghosh …

We calculate the normalized vacuum energy density for a massless scalar field confined in a
region limited by two parallel plates, placed in the background spacetime generated by a …

Nesta tese, estudamos algumas configurações de buracos negros com quintessência e/ou
nuvem de cordas na relatividade geral e na gravitação de Lovelock. Iniciamos fazendo uma …
