Moritz, F. Mila, and T. P. Devereaux Phys. Rev. B 96, 195106 – Published 2 November 2024 More PDF HTML Export Citation Abstract WebThe Hubbard model can be studied within dynamical mean-field theory (DMFT). This scheme maps the Hubbard Hamiltonian onto a single-site impurity model, a mapping that is formally exact only in infinite dimensions and in finite dimensions corresponds to the exact treatment of all purely local correlations only.

WebThe dynamics is independent of the sign of the interaction, revealing a novel, dynamic symmetry of the Hubbard model. I n solid-state physics, transport properties are among the key observables, the most prominent example being the electri-cal conductivity, which, for example, allows one to distin- WebNext, we studied the dynamics of the model. Using the wide-gapped band structure of the Bose-Hubbard spectrum, we provide an approximate description of the dynamics within each band. The dynamics effectively occur within a single band, resulting in various forms of collective behaviour, such as bosons on a single site moving as a single ...
