DESCRIPTION: The macroscopic polarization of a solid is an fundamental quan
 tity from which permittivity and piezoelectric tensors can be derived. The
  Berry phase formula of King-Smith and Vanderbilt expresses the macroscopi
 c polarization in terms of the Bloch states of a mean-field band structure
 \, almost invariably taken from density functional theory. Although this p
 rocedure has been successful for many materials\, quantum fluctuations cau
 se it to break down in strongly correlated systems.\nVortragende(r): Ryan
