Berry Flux Diagonalization: Application to Electric Polarization

1 code implementation7 Feb 2020 John Bonini, David Vanderbilt, Karin M. Rabe

In this work, we present a physically motivated approach for predicting the experimentally measured switching polarization that involves separating the change in phase between two states into as many gauge-invariant smaller phase changes as possible.

Surfaces of Axion Insulators

no code implementations8 Sep 2018 Nicodemos Varnava, David Vanderbilt

In the case of AIAO ordering, we show that it is possible to construct a topological state with no protected metallic states on boundaries of any dimension (surfaces, hinges, or corners), although chiral hinge modes do occur for many surface configurations.
