Spin-phonon coupling effects in transition-metal perovskites:a DFT+ and hybrid-functional study
Jiawang Hong, Alessandro Stroppa, Jorge Íñiguez +2
Spin-phonon coupling effects, as reflected in phonon frequency shifts between ferromagnetic (FM) and G-type antiferromagnetic (AFM) configurations in cubic CaMnO, SrMnO, Ba…

First-principles theory of frozen-ion flexoelectricity
Jiawang Hong, David Vanderbilt
We demonstrate that the frozen-ion contribution to the flexoelectric coefficient is given solely in terms of the sum of third moments of the charge density distortions induced by a…

Mapping the energy surface of PbTiO3 in multidimensional electric-displacement space
Jiawang Hong, David Vanderbilt
In recent years, methods have been developed that allow first-principles electronic-structure calculations to be carried out under conditions of fixed electric field. For some purp…
