[ALPS-users] Can the mps_optim calculate the entanglement spectrum of the lattice with two cuts ?

[Michele Dolfi]

Hello,

The entanglement spectrum with the mps_optim application can be computed only on the connection between two sites in the “effective one dimensional structure” of the ansatz.


Best,
Michele
