Entanglement Criteria for All Bipartite Gaussian States
TL;DR: In this article, a necessary and sufficient condition for separability of Gaussian states of bipartite systems of arbitrarily many modes is provided. But this condition can be checked by simple computation, and it can be used to find a pure product-state decomposition of any given separable Gaussian state.
Unconventional quantum optics in topological waveguide QED
TL;DR: In this paper, the authors predict several quantum optical phenomena that occur when quantum emitters interact with a topological waveguide quantum electrodynamics bath, namely, the photonic analog of the Su-Schrieffer-Heeger model.
Mapping local Hamiltonians of fermions to local Hamiltonians of spins
Frank Verstraete,J. I. Cirac +1 more
TL;DR: In this paper, the Jordan-Wigner transformation was extended to dimensions higher than one by introducing auxiliary degrees of freedom, represented by Majorana fermions, which allowed the transformation to be applied to local spin problems on a lattice in any dimension.
Quasi-Many-Body Localization in Translation-Invariant Systems.
TL;DR: A single length scale is identified which parametrically controls both the spin transport times and the apparent divergence of the susceptibility to spin glass ordering, which persists over many orders of magnitude in time, quasi-many-body localization.

Hawking Radiation from an Acoustic Black Hole on an Ion Ring
TL;DR: This Letter proposes to simulate acoustic black holes with ions in rings with a stationary and inhomogeneous velocity profile and studies the appearance of Hawking radiation in this setup and proposes a scheme to detect it.
