Abstract:
We derive the semiclassical Bloch dynamics with the second order Berry
phase correction, based on a two-scale WKB asymptotic analysis. For
uniform external electric field, the bi-characteristics system after
a positional shift introduced by Berry connections agrees with the
recent result in the physics literature. |
