摘要
Displaced states for neutral particles which possess a permanent electric dipole moment are built in the presence of a magnetic field. Then, by performing an adiabatic cyclic evolution, it is shown that Abelian and non-Abelian Berry phases can be obtained for the displaced states based on the Landau-He-McKellar-Wilkens quantization (L.R. Ribeiro et al., Phys. Lett. A 348, 135 (2006)).
