Paper Abstract

Wannier functions are real space basis functions which are not unique due to an arbitrary phase factor in the Bloch envelope function. We exploit this property to optimize a spread functional numerically using an accelerated steepest descent, and obtain the maximally confined set of Wannier functions, which are obtained for the first time in the area of planar plasmonics and conducting interfaces.
