Viscoelastic response of topological tight-binding models in two and three dimensions
Viscoelastic response of topological tight-binding models in two and three dimensions
The topological response to external perturbations is an effective probe to characterize different topological phases of matter. Besides the Hall conductance, the Hall viscosity is another example of such a response that measures how electronic wave functions respond to changes in the underlying geometry. Topological (Chern) insulators are known to …
