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 …
A bstract The entanglement negativity\(\mathcal {E}\)(A: B) is a useful measure of quantum entanglement in bipartite mixed states. In random tensor networks (RTNs), which are related …
A bstract We investigate how entanglement in the mixed state of a quantum field theory can be described using the cross-computable norm or realignment (CCNR) criterion, employing …

We calculate the amount of entanglement shared by two intervals in the ground state of a (1+ 1)-dimensional conformal field theory (CFT), quantified by an entanglement measure E …

A bstract We study the reflected entropy in (1+ 1)-dimensional Lifshitz field theory whose groundstate is described by a quantum mechanical model. Starting from tripartite Lifshitz …
Quantum entanglement is a particularly useful characterization of topological orders which lack conventional order parameters. In this work, we study the entanglement in topologically …
For general random tensor network states at large bond dimension, we prove that the integer R\'enyi reflected entropies (away from phase transitions) are determined by minimal …

Understanding the entanglement structure of holographic states has played a significant role in demystifying quantum gravity and the emergence of spacetime. The state of the art …
