Self-organization in many-body systems with short-range interactions: clustering, correlations and topology
Ioannis Kleftogiannis, Ilias Amanatidis
We investigate the self-organization of point-particles with short-range interactions modeled via simple 1D and 2D Hubbard-like models. We show how various properties emerge such a…

Exact results for the entanglement in 1D Hubbard models with spatial constraints
Ioannis Kleftogiannis, Ilias Amanatidis, Vladislav Popkov
We investigate the entanglement in Hubbard models of hardcore bosons in , with an additional hardcore interaction on nearest neighbouring sites. We derive analytical formulas f…
