Multipartite entanglement spreads
The entanglement structure of a bipartite pure state is characterized by its entanglement spectrum, or equivalently, by the family of R\'{e}nyi-$k$ entanglement entropies with integer $k$. Taking the difference of two such entropies defines a quantity known as an entanglement spread, that is monotonous under local oper...
