Mott transition in the dynamic Hubbard model within slave boson mean-field approach

In the paper "Mott transition in the dynamic Hubbard model within slave boson mean-field approach", the influences of the dynamics of the auxiliary boson field on the Mott transition are investigated. At finite boson frequency, the Mott-type features of the Hubbard model is found to be enhanced by increasing the pseudospin coupling parameter g. |
