Scalar particles around a Rindler-Schwarzschild wormhole
C. R. Muniz, H. R. Christiansen, M. S. Cunha +2
In this paper, we study quantum relativistic features of a scalar field around the Rindler-Schwarzschild wormhole. First, we introduce this new class of spacetime, investigating so…
Four-dimensional regular black strings in bilocal gravity
C. R. Muniz, H. R. Christiansen, M. S. Cunha +1
In this paper, we obtain a static black string solution for a bilocal gravitational source in 3+1 dimensions. The solution is regular at the origin and tends asymptotically to the…
New regular 2+1 black hole solutions from bilocal gravity
H. R. Christiansen, Milko Estrada, M. S. Cunha +2
We obtain new regular black hole solutions for an action in 2+1 dimensions with bilocal Ricci scalar and negative cosmological constant. Besides their connection to the cosmologica…
Class of solutions of the Wheeler-DeWitt equation with ordering parameter
H. S. Vieira, V. B. Bezerra, C. R. Muniz +2
In this letter, we discuss the Wheeler-DeWitt equation with an ordering parameter in the Friedmann-Robertson-Walker universe. The solutions when the universe was very small and at…
Exact solutions of the Wheeler-DeWitt equation with ordering term in a dark energy scenario
C. R. Muniz, H. R. Christiansen, M. S. Cunha +1
We investigate the quantum evolution of the universe in the presence of two types of dark energies. First, we consider the phantom class () which would be responsible for a s…
Thermal Casimir effect in Kerr spacetime with quintessence and massive gravitons
V. B. Bezerra, H. R. Christiansen, M. S. Cunha +2
Starting from an analytical expression for the Helmholtz free energy we calculate the thermal corrections to the Casimir energy-density and entropy within nearby ideal parallel pla…
