Dynamics hubbard model
WebAn important example is the Hubbard model, which describes interacting electrons in narrow energy bands, and which has been applied to problems as diverse as high-Tc superconductivity, band magnetism, and the metal-insulator transition. This book presents a coherent, self-contained account of the exact solution of the Hubbard model in one ... WebFor both the Fermi–Hubbard model (figure 3) and the Fermi–Bose model (figure 5), we observed a doubling of the practical simulation time. These numerical results are very encouraging, and they could, for example, trigger an investigation of the ex-act quantum dynamics of large 2D Fermi–Hubbard models.

WebThis book gathers a collection of reprints on the Hubbard Model. The major contributions to the subject since its origin are included, with the aim of providing all scientists working on the model and its applications with easy access to the relevant literature. The book is … 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 ...
The Hubbard model is an approximate model used to describe the transition between conducting and insulating systems. It is particularly useful in solid-state physics. The model is named for John Hubbard. The Hubbard model states that each electron experiences competing forces: one pushes it to tunnel to neighboring atoms, while the other pushes it away fr…
