On Berry Phase in Bloch States
arXiv:cond-mat/0209532 · doi:10.1016/S1386-9477(02)01076-7
Abstract
We comment on the relation between Berry phase and quantized Hall conductivities for charge and spin currents in some Bloch states, such as Bloch electrons in the presence of electromagnetic fields and quasiparticles in the vortex states of superfluid He. One can find out that the arguments presented here are closely related to the spontaneous polarization in crystalline dielectrics and the adiabatic pumping.
