Random-matrix perspective on many-body entanglement with a finite localization length
Random-matrix perspective on many-body entanglement with a finite localization length
We provide a simple and predictive random-matrix framework that naturally generalizes Page's law for ergodic many-body systems by incorporating a finite entanglement localization length. By comparing a highly structured one-dimensional model to a completely unstructured model and a physical system, we uncover a remarkable degree of universality, suggesting that the …
