# Metal-insulator transition caused by coupling to localized charge-frustrated systems under ice-rule local constraint

@article{Ishizuka2011MetalinsulatorTC, title={Metal-insulator transition caused by coupling to localized charge-frustrated systems under ice-rule local constraint}, author={Hiroaki Ishizuka and Masafumi Udagawa and Yukitoshi Motome}, journal={Physical Review B}, year={2011}, volume={83} }

We report the results of our theoretical and numerical study on electronic and transport properties of fermion systems with charge frustration. We consider an extended Falicov-Kimball model in which itinerant spinless fermions interact repulsively by U with localized particles whose distribution satisfies a local constraint under geometrical frustration, the so-called ice rule. We numerically calculate the density of states, optical conductivity, and inverse participation ratio for the models…

A real space Monte Carlo based approach is used to study the model at finite temperature, and temperature-interaction phase diagrams are established that highlight the Mott transition, orbital ordering, and spectral trends, and possible window of pseudogap.

The electronic structure is compared with the numerical results for the pyrochlore-lattice model to elucidate the physics of electron systems interacting with the tetrahedron ice rule and reveals a quantum critical point with the emergence of non-Fermi-liquid behavior in melting of the "charge ice" insulator.

Metallic spin-liquid behavior of the geometrically frustrated Kondo lattice.

The results indicate that the underscreened moments show spin-liquid behavior below a renormalized correlation scale of 1.7 K, and the Kondo effect emerges and leads to a partial screening of the moments below /T*/.

It is conjecture that a local constraint obeyed by the extensively degenerate ground states dictates a dipolar form for the asymptotic spin correlations, at all N not equal 2 for which the system is paramagnetic down to T=0.
