Implications on the cosmic coincidence by a dynamical extrinsic curvature
A. J. S Capistrano, L. A. Cabral
In this work, we apply the smooth deformation concept in order to obtain a modification of Friedmann equations. It is shown that the cosmic coincidence can be at least alleviated u…
Why the measured cosmological constant is small
T. Rostami, S. Jalalzadeh
In a quest to explain the small value of the today's cosmological constant, following the approach introduced in [1], we show that the theoretical value of cosmological constant is…
Quantum cosmological intertwining: Factor ordering and boundary conditions from hidden symmetries
T. Rostami, S. Jalalzadeh, P. V. Moniz
We explore the implications of hidden symmetries present in a particular quantum cosmological setting, extending the results reported in \cite{10,11}. In more detail, our case stud…
On the thermal stability of a static spherically symmetric black holes in Nash embedding framework
Abraão J. S Capistrano, Antonio C. Gutiérrez-Piñeres, Sergio C. Ulhoa +1
We study the deformation caused by the influence of extrinsic curvature on a vacuum spherically symmetric metric embedded in a five-dimensional bulk. In this sense, we investigate…
Inflexibility and independence: Phase transitions in the majority-rule model
Nuno Crokidakis, Paulo Murilo Castro de Oliveira
In this work we study opinion formation in a population participating of a public debate with two distinct choices. We considered three distinct mechanisms of social interactions a…
Drag force in wind tunnels: a new method
P. V. S. Souza, Daniel Girardi, P. M. C. de Oliveira
A rigid object of general shape is fixed inside a wind tunnel. The drag force exerted on it by the wind is determined by a new method based on simple basic Physics concepts, provid…
Domain size heterogeneity in the Ising model: geometrical and thermal transitions
André R. de la Rocha, Paulo Murilo C. de Oliveira, Jeferson J. Arenzon
A measure of cluster size heterogeneity (), introduced by Lee et al [Phys. Rev. E {\bf 84}, 020101 (2011)] in the context of explosive percolation, was recently applied to rando…
