seemps.state.CanonicalMPS.update_2site_left#
method
- CanonicalMPS.update_2site_left(AA, site, strategy)[source]#
Split a two-site tensor into two one-site tensors by left orthonormalization and insert the tensor in canonical form into the MPS Ψ at the given site and the site on its right. Update the neighboring sites in the process.
- Parameters:
- AA
Tensor4 Two-site tensor A[a,i,j,b]
- site
int The index of the site whose quantum number is i. The new center will be self.site.
- strategy
Strategy Truncation strategy, including relative tolerances and maximum bond dimensions
- AA
