Microscopic theory of Chern polarization via crystalline defect charge
Thivan M. Gunawardana, Frank Schindler, Ari M. Turner +1
The modern theory of polarization does not apply in its original form to systems with non-trivial band topology. Chern insulators are one such example. Defining polarization for th…

Optimally Localized Wannier Functions for 2D Chern Insulators
Thivan M. Gunawardana, Ari M. Turner, Ryan Barnett
The construction of optimally localized Wannier functions (and Wannier functions in general) for a Chern insulator has been considered to be impossible owing to the fact that the s…
