The Fate of Entanglement
Gilles Parez, William Witczak-Krempa
Quantum entanglement manifests itself in non-local correlations between the constituents of a system. In its simplest realization, a measurement on one subsystem is affected by a p…
Entanglement negativity between separated regions in quantum critical systems
Gilles Parez, William Witczak-Krempa
We study the entanglement between disjoint subregions in quantum critical systems through the lens of the logarithmic negativity. We work with systems in arbitrary dimensions, incl…
Reflected entropy and computable cross-norm negativity: Free theories and symmetry resolution
Clément Berthiere, Gilles Parez
We investigate a separability criterion based on the computable cross-norm (CCNR), and a related quantity called the CCNR negativity. We introduce a reflected version of the CCNR n…
Separability and entanglement of resonating valence-bond states
Gilles Parez, Clément Berthiere, William Witczak-Krempa
We investigate separability and entanglement of Rokhsar-Kivelson (RK) states and resonating valence-bond (RVB) states. These states play a prominent role in condensed matter physic…
On the logarithmic bipartite fidelity of the open XXZ spin chain at
Christian Hagendorf, Gilles Parez
The open XXZ spin chain with the anisotropy and a one-parameter family of diagonal boundary fields is studied at finite length. A determinant formula for an overlap in…
