Parameter estimation in an anisotropic expanding spacetime
O. P. de Sá Neto, I. G. da Paz, P. R. S. Carvalho +1
In this work, we investigate how the anisotropy affects the cosmological parameters estimation. Here the anisotropy is incorporated as a small gravitational disturbance. We calcula…

Parameter estimation for a Lorentz invariance violation
H. A. S. Costa, P. R. S. Carvalho, I. G. da Paz
We employ techniques from quantum estimation theory (QET) to estimate the Lorentz violation parameters in the 1+3-dimensional flat spacetime. We obtain and discuss the expression o…
