Constraints on the general solutions of Einstein cosmological equations by Hubble parameter times cosmic age: a historical perspective
Julio A. Gonzalo, Manuel Alfonseca
In a historical perspective, compact solutions of Einstein's equations, including the cosmological constant and the curvature terms, are obtained, starting from two recent observat…
Is a non-vanishing cosmological constant really needed?
Julio A. Gonzalo
Using consistenly the compact Friedmann-Lemaitre solutions for an open universe with zero cosmological constant () we show that the oberved apparent accelerated…
Behavior of the local mode potential in BaTiO3 studied by Effective Hamiltonian numerical simulations
Manuel I. Marques, Julio A. Gonzalo
The behavior of the local mode potential energy in the unit cell of BaTiO3 is studied by effective Hamiltonian numerical simulations. The study is focused on the evolution of the p…
The quantum paraelectric behavior of SrTiO_{3} revisited: relevance of the structural phase transition temperature
Manuel I. Marques, Carmen Arago, Julio A. Gonzalo
It has been known for a long time that the low temperature behavior shown by the dielectric constant of quantum paraelectric can not be fitted properly by Barrett's for…
Finite size scaling and equation of state for Ising lattices
J. G. Garcia, J. A. Gonzalo
Accurate Monte Carlo data from a set of isotherms near the critical point are analyzed using two RG based complementary representations, given respectively in terms of $\bar h=h/\m…
Effective Critical Exponents of Ising Strips D*L with D<<L
M. Felisa Martinez, Carlos Garcia, Julio A. Gonzalo
Monte Carlo data simulating phase transitions in Ising strips ($D\llL) $ with periodic boundary conditions show that for and $0<T…
