Mott Transition in the Hubbard Model
In this article, I discuss W.Kohn’s criterion for a metal insulator transition, within the framework of a one band Hubbard model. This and related ideas are applied to 1-dimensional Hubbard systems, and some intersting miscellaneous results discussed. The Jordan Wigner transformation converting the two species of fermions to two species of hardcore bosons is performed in detail, and the “extra ...
متن کاملMott transition in kagomé lattice Hubbard model.
We investigate the Mott transition in the kagomé lattice Hubbard model using a cluster extension of dynamical mean field theory. The calculation of the double occupancy, the density of states, and the static and dynamical spin correlation functions demonstrates that the system undergoes the first-order Mott transition at the Hubbard interaction U/W approximately 1.4 (W:bandwidth). In the metall...
متن کاملMass enhancement and magnetic order at the Mott-Hubbard transition.
We study the evolution with pressure P and band filling y of the heat capacity, Hall coefficient, and resistivity at the approach to the T~O Mott-Hubbard metal-insulator transition (MIT) in highly correlated V2 ~03. Under P, the electronic effective mass m diverges at the MIT with a negligible change in carrier concentration n away from half-filling. Conversely, in the doped system m actually d...
متن کاملDimensional-crossover-driven Mott transition in the frustrated Hubbard model.
We study the Mott transition in a frustrated Hubbard model with next-nearest neighbor hopping at half-filling. The interplay between interaction, dimensionality, and geometric frustration closes the one-dimensional Mott gap and gives rise to a metallic phase with Fermi surface pockets. We argue that they emerge as a consequence of remnant one-dimensional umklapp scattering at the momenta with v...
متن کاملThe Mott-Hubbard transition and the paramagnetic insulating state in the two-dimensional Hubbard model
– The Mott-Hubbard transition is studied in the context of the two-dimensional Hubbard model. Analytical calculations show the existence of a critical value Uc of the potential strength which separates a paramagnetic metallic phase from a paramagnetic insulating phase. Calculations of the density of states and double occupancy show that the ground state in the insulating phase contains always a...
