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…
Temperature estimation of an entangled pair of trapped ions
O. P. de Sá Neto, H. A. S. Costa, G. A. Prataviera +1
We apply estimation theory to a system formed by two interacting trapped ions. By using the Fisher matrix formalism, we introduce a simple scheme for estimation of the temperature…
Diffeomorphism symmetry effect on the O(N ) universality class
H. A. S. Costa, P. R. S. Carvalho
We probe the effect of diffeomorphism symmetry on the critical exponents values for massive O() scalar field theories in curved spacetime. We apply field-theoretic reno…
