28 Oct 2020 | | Abstract: | In this work, we present a quantum information framework for the entanglement
behavior of the low energy quasiparticle (QP) excitations in various quantum
phases in one-dimensional (1D) systems. We first establish an exact
correspondence between the correlation matrix and the QP entanglement
Hamiltonian for free fermions and find an extended in-gap state in the QP
entanglement Hamiltonian as a consequence of the position uncertainty of the
QP. A more general understanding of such an in-gap state can be extended to a
Kramers theorem for the QP entanglement Hamiltonian, which also applies to
strongly interacting systems. Further, we present a set of ubiquitous
entanglement spectrum features, dubbed entanglement fragmentation, conditional
mutual information, and measurement induced non-local entanglement for QPs in
1D symmetry protected topological phases. Our result thus provides a new
framework to identify different phases of matter in terms of their QP
entanglement. | | Source: | arXiv, 2010.15137 | | Services: | Forum | Review | PDF | Favorites | |
