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…
