Ab-initio theories like Density Functional Theory (DFT) have been remarkably successful in predicting a wide range of material properties. However, the tremendous computational expense associated with these first-principles calculations severely restricts the size of systems that can be studied. In fact, routine DFT simulations are typically limited to a few hundred atoms. As a result, most mechanics-related problems of interest are intractable using approaches traditionally employed in DFT.

Topological transport of sound waves and vibrations in solids has attracted considerable attention in the past two years. Several approaches have been proposed and some have been demonstrated. However, it remains an outstanding challenge to create platforms for topological transport of phonons at the nanoscale. In this talk, I will describe three possible approaches that we have proposed. In the first, time-reversal is broken explicitly, with the help of an external laser field containing optical vortices.
