Ferromagnetism in Hubbard Models [PDF]
Physical Review Letters, 1995 We present the first rigorous examples of non-singular Hubbard models which exhibit ferromagnetism at zero temperature. The models are defined in arbitrary dimensions, and are characterized by finite-ranged hoppings, dispersive bands, and finite on-site Coulomb interaction U.

Recent Progress in Lattice Density Functional Theory
Computation, 2019 Recent developments in the density-functional theory of electron correlations in many-body lattice models are reviewed. The theoretical framework of lattice density-functional theory (LDFT) is briefly recalled, giving emphasis to its universality and to ...

On integrability of the one-dimensional Hubbard model
Physics Letters B, 2023 We find a family of solutions to Zamolodchikov's tetrahedral algebra corresponding to the fermionic R-operator for the free fermion model of the difference type in one of the spectral parameters, construct an extension of the R-operator for a system of ...

Advanced Functional Materials, EarlyView.Programmable 2D magnetic clusterphenes are realized through a ligand‐mediated cluster‐assembly strategy. Direct linking of magnetic superatomic clusters enhances electron delocalization and symmetry breaking, enabling the concurrent strengthening of magnetic exchange interactions and spin–orbit coupling.
