Mott Transition in the Two-Dimensional Hubbard Model

Masanori Kohno

Spectral properties of the two-dimensional Hubbard model near the Mott transition are investigated by using cluster perturbation theory. The Mott transition is characterized by freezing of the charge degrees of freedom in a single-particle excitation that leads continuously to the magnetic excitation of the Mott insulator. Various anomalous spectral features observed in cuprate high-temperature superconductors are explained in a unified manner as properties near the Mott transition.

Mott transition in the one-dimensional SU (n) Hubbard model

E. Szirmai, Jenő Sólyom

The one-dimensional SU$(n)$ Hubbard model is investigated using an analytical, perturbative renormalization-group treatment in the fermionic formulation of the model for $n>2$. It is found that in the half-filled case, the umklapp processes couple the spin and charge degrees of freedom and generate a finite gap for arbitrary finite positive $U$. This behavior is thus different from that at $1∕n$ filling, where there is one particle per site, in which case the dynamics of the two degrees of freedom can be separated and a critical ${U}_{\mathrm{c}}$ is needed for the Mott transition.

MOTT TRANSITION IN THE HUBBARD MODEL

WORLD SCIENTIFIC eBooks•Apr 1, 1993•0 citations
The one-dimensional SU(n)(n)(n) Hubbard model is investigated using an analytical, perturbative renormalization-group treatment in the fermionic formulation of the model for n>2n>2n>2. It is found that in the half-filled case, the umklapp processes couple the spin and charge degrees of freedom and generate a finite gap for arbitrary finite positive UUU. This behavior is thus different from that at 1∕n1∕n1∕n filling, where there is one particle per site, in which case the dynamics of the two degrees of freedom can be separated and a critical Uc{U}_{\mathrm{c}}Uc​ is needed for the Mott transition.
