A simple efficient algorithm in frustration-free one-dimensional gapped systems
arXiv:1510.01303
Abstract
We propose an efficient algorithm for the ground state of frustration-free one-dimensional gapped Hamiltonians. This algorithm is much simpler than the original one by Landau et al., and thus may be easily accessible to a general audience in the community. We present all the details in two pages.
