The Dissipative Bose-Hubbard Model. Methods and Examples
G. Kordas, D. Witthaut, P. Buonsante +4
Open many-body quantum systems have attracted renewed interest in the context of quantum information science and quantum transport with biological clusters and ultracold atomic gas…
Quantum signatures of self-trapping transition in attractive lattice bosons
P. Buonsante, V. Penna, A. Vezzani
We consider the Bose-Hubbard model describing attractive bosonic particles hopping across the sites of a translation-invariant lattice, and compare the relevant ground-state proper…
Diffusive Thermal Dynamics for the Ising Ferromagnet
P. Buonsante, R. Burioni, D. Cassi +1
We introduce a thermal dynamics for the Ising ferromagnet where the energy variations occurring within the system exhibit a diffusive character typical of thermalizing agents such…
Topological Reduction of Tight-Binding Models on Complex Networks
P. Buonsante, R. Burioni, D. Cassi
Complex molecules and mesoscopic structures are naturally described by general networks of elementary building blocks and tight-binding is one of the simplest quantum model suitabl…
