# Bulk Entanglement and Boundary Spectra in Gapped Topological Phases

@article{Luo2018BulkEA, title={Bulk Entanglement and Boundary Spectra in Gapped Topological Phases}, author={Zhu-Xi Luo and Brendan G. Pankovich and Yuting Hu and Yong -Shi Wu}, journal={arXiv: Strongly Correlated Electrons}, year={2018} }

We study the correspondence between boundary spectrum of non-chiral topological orders on an open manifold $\mathcal{M}$ with gapped boundaries and the entanglement spectrum in the bulk of gapped topological orders on a closed manifold. The closed manifold is bipartitioned into two subsystems, one of which has the same topology as $\mathcal{M}$. Specifically, we focus on the case of generalized string-net models and discuss the cases where $\mathcal{M}$ is a disk or a cylinder. The…

It is proposed that gapped boundary conditions of the surface are in one-to-one correspondence with the sets of condensates, each being able to completely break the phase, and generalized pumping may find applications in quantum control of anyons, eventually realizing topological quantum computation.
