Z_N Berry phase and symmetry protected topological phases of SU(N) antiferromagnetic Heisenberg chain

Yuichi Motoyama, Synge Todo

The local Z_N quantized Berry phase for the SU(N) antiferromagnetic Heisenberg spin model is formulated. This quantity, which is a generalization of the local Z_2 Berry phase for S…
