The quasi-particle picture and its breakdown after local quenches: mutual information, negativity, and reflected entropy
A bstract We study the dynamics of (Rényi) mutual information, logarithmic negativity, and (Rényi) reflected entropy after exciting the ground state by a local operator. Together with recent results from ref. [1], we are able to conjecture a close-knit structure between the three quantities that emerges in states excited above …
