Berry Flux Diagonalization: Application to Electric Polarization

7 Feb 2020John BoniniDavid VanderbiltKarin M. Rabe

The switching polarization of a ferroelectric is a characterization of the current that flows due to changes in polarization when the system is switched between two states. Computation of this change in polarization in crystal systems has been enabled by the modern theory of polarization, where it is expressed in terms of a change in Berry phase as the material switches...
