Unsupervised detection of decoupled subspaces: many-body scars and beyond
Tomasz Szołdra, Piotr Sierant, Maciej Lewenstein +1
Highly excited eigenstates of quantum many-body systems are typically featureless thermal states. Some systems, however, possess a small number of special, low-entanglement eigenst…
