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…
