Dr. Gianluca Panati (La Sapienza, Universita' di Roma)
"Geometric currents in piezoelectricity"
Abstract: Multiscale and adiabatic methods play a fundamental role in the
analysis of physical systems. In the talk, I will illustrate this
principle, at a non technical level, in the specific case of
piezoelectricity.
As a simple model for piezoelectricity we consider a gas of
noninteracting electrons subject to a slowly varying time-dependent
periodic potential. We will see that in the adiabatic limit the
macroscopic current is determined by the geometry of the Bloch
bundle. As a consequence we obtain the King-Smith and Vanderbilt formula
up to errors smaller than any power of the adiabatic parameter.
