From quantum to classical via crystallization
Ioannis Kleftogiannis, Ilias Amanatidis
We show that classical states can emerge as pure ground state solutions of a quantum many-body system. We use a simple Hubbard model in 1D with strong short-range interactions and…
Energetical self-organization of a few strongly interacting particles
Ioannis Kleftogiannis, Ilias Amanatidis
We study the quantum self-organization of a few interacting particles with strong short-range interactions. The physical system is modeled via a 2D Hubbard square lattice model, wi…
Fractional-quantum-Hall-effect (FQHE) in 1D Hubbard models
Ioannis Kleftogiannis, Ilias Amanatidis
We study the quantum self-organization of interacting particles in one-dimensional(1D) many-body systems, modeled via Hubbard chains with short-range interactions between the parti…
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…
Topological self-organization of strongly interacting particles
Ioannis Kleftogiannis, Ilias Amanatidis
We investigate the self-organization of strongly interacting particles confined in 1D and 2D. We consider hardcore bosons in spinless Hubbard lattice models with short-range intera…
Entanglement and edge effects in superpositions of many-body Fock states with spatial constraints
Ioannis Kleftogiannis, Ilias Amanatidis
We investigate how entangled states can be created by considering collections of point-particles arranged at different spatial configurations, i.e., Fock states with spatial constr…
