Entanglement spectra of the q-deformed Affleck-Kennedy-Lieb-Tasaki model and matrix product states
Raul A. Santos, Francis N. C. Paraan, Vladimir E. Korepin +1
We exactly calculate the reduced density matrix of matrix product states (MPS). Our compact result enables one to perform analytic studies of entanglement in MPS. In particular, we…

Entanglement of disjoint blocks in the one dimensional Spin 1 VBS
Raul A. Santos, Vladimir Korepin
Starting with the valence bond solid (VBS) ground state of the 1D AKLT Hamiltonian, we make a partition of the system in 2 subsystems and , where is a block of conse…

Negativity for two blocks in the one dimensional Spin 1 AKLT model
Raul A. Santos, V. Korepin, Sougato Bose
In this paper we compute the entanglement, as quantified by negativity, between two blocks of length and , separated by sites in the one dimensional spin-1 AKLT mode…
