Efficient representation of fully many-body localized systems using tensor networks

Understand

We propose a tensor network encoding the set of all eigenstates of a fully many-body localized system in one dimension.

• Our construction, conceptually based on the ansatz introduced in Phys.
• Rev.
• B 94, 041116(R) (2016), is built from two layers of unitary matrices which act on blocks of $\ell$ contiguous sites.
