This collection of articles provides authoritative and up-to-date reviews on the Hubbard Model. It will be useful to graduate students and researchers in the field. Contents: The Phase Diagram of the Hubbard Model (M W Long) Netteta quantitative formulation we now outline an approach which, by taking corre lation effects into account in the band model, leads to a localized description. This approach is precisely the Hubbard model which he originally introduced as a microscopic model to explain the Mott transition. The basic ingredient of the model is a collection of ...
[2207.06297] Instanton gas approach to the Hubbard model
Nettet28. mar. 2024 · In previous work, we have applied the instanton approach to various model systems including asymmetric system-bath models of electron transfer and photodissociation in anharmonic potentials . The results compared favourably with quantum-mechanical benchmarks and were seen to be much more accurate than … Nettet18. jan. 2024 · This is mainly because none of the analytical approaches devel-oped to determine the stationary state of out-of-equilibrium integrable systems [24–27]can be applied to the Hubbard model with finite interaction strength due to its technical complexity. In essence, the evolution of the Hubbard model has been accessed only … city of ottawa indoor public skating
