WebA tensor in a network definition. To remove a tensor from a network definition, use INetworkDefinition::removeTensor (). When using the DLA, the cumulative size of all Tensors that are not marked as Network Input or Output tensors, must be less than 1GB in size to fit into a single subgraph. WebTo help with the logic of 2D lattices, ITensor pre-defines some helper functions which return an array of bonds. Each bond object has an "s1" field and an "s2" field which are the integers numbering the two sites the bond connects.

WebAn ITensor is a tensor whose interface is independent of its memory layout. Therefore it is not necessary to know the ordering of an ITensor's indices, only which indices an ITensor has. Operations like contraction and addition of ITensors automatically handle any memory permutations. Examples Webinc/ipeps contains the IPEPSv1 code, relying on standard syten::Tensor objects. inc/ipeps2 contains the IPEPSv2 code, which uses syten::STensor to handle contractions (and also fermions) in a more straightforward manner. inc/alg …
