Dynamic flexoelectric effect in perovskites from first principles calculations
Alexander Kvasov, Alexander K. Tagantsev
Using the dynamical matrix of a crystal obtained from ab initio calculations, we have evaluated for the first time the strength of the dynamic flexoelectric effect and found it com…

Positive effective Q12 electrostrictive coefficient in perovskites
Alexander Kvasov, Alexander K. Tagantsev
It is demonstrated that for classical perovskites such as BaTiO3, SrTiO3 and PbTiO3 electrostrictive strain induced by an electric field may not obey traditionally considered "exte…

Can we trust the temperature - misfit strain thin film phase diagrams?
Alexander Kvasov, Alexander K. Tagantsev
Currently used methods for the description of thermodynamics of ferroelectric thin films (Landau theory or ab initio based Monte-Carlo simulations) are based on an energy expansion…
