Enhanced protected topological states (IMAGE) DOE/Ames National Laboratory Caption Ames Laboratory scientists took a paradoxical approach, called dynamic stabilization, by applying a terahertz electric field to drive periodic lattice oscillations in a model topological insulator. These additional fluctuations actually enhanced protected topological states.
