Non-Abelian cosmic string in the Starobinsky model of gravity
J. P. Morais Graça, A. de Pádua Santos, Eugênio R. Bezerra de Mello +1
In this paper, we analyze numerically the behaviour of the solutions corresponding to a non-Abelian cosmic string in the framework of the Starobinsky model, i.e. where $f(R)=R + ζR…
Casimir effects in Lorentz-violating scalar field theory
M. B. Cruz, E. R. Bezerra de Mello, A. Yu. Petrov
In this paper we consider a Lorentz-breaking extension of the theory for a real massive scalar quantum field in the region between two large parallel plates, with our manner to bre…
Quantum Brownian motion in an analog Friedmann-Robertson-Walker geometry
C. H. G. Bessa, V. B. Bezerra, E. R. Bezerra de Mello +1
In this paper we study the effects of quantum scalar field vacuum fluctuations on scalar test particles in an analog model for the Friedmann-Robertson-Walker spatially flat geometr…
Scalar Casimir effect in a high-dimensional cosmic dispiration spacetime
H. F. Mota, E. R. Bezerra de Mello, K. Bakke
In this paper we present a complete and detailed analysis of the calculation of both the Wightman function and the vacuum expectation value of the energy-momentum tensor that arise…
The Casimir effect for parallel plates in Friedmann-Robertson-Walker universe
E. R. Bezerra de Mello, A. A. Saharian, M. R. Setare
We evaluate the Hadamard function, the vacuum expectation values (VEVs) of the field squared and the energy-momentum tensor for a massive scalar field with general curvature coupli…
