Abelian-symmetric generic Kagome iPESSΒΆ
Specialized sub-class of ipeps.ipeps_kagome_abelian.IPEPS_KAGOME_ABELIAN
.
A single on-site tensor representing DoFs on down triangle is built from
five different tensors: two rank-3 trivalent tensors with only auxiliary indices
and three rank-3 bond tensors, each associated to one of the physical DoFs on the vertices of the down triangle.
