Entanglement Content of Quantum Particle Excitations III. Graph Partition Functions
Olalla A. Castro-Alvaredo, Cecilia De Fazio, Benjamin Doyon +1
We consider two measures of entanglement, the logarithmic negativity and the entanglement entropy, between regions of space in excited states of many-body systems formed by a finit…

Entanglement in permutation symmetric states, fractal dimensions, and geometric quantum mechanics
Olalla A. Castro-Alvaredo, Benjamin Doyon
We study the von Neumann and Rényi bipartite entanglement entropies in the thermodynamic limit of many-body quantum states with spin-s sites, that possess full symmetry under excha…
