Magnetic and charge susceptibilities in the half-filled triangular lattice Hubbard model
Shaozhi Li, Emanuel Gull
Abstract
The authors provide theoretical results of the dynamic magnetic susceptibility in the triangular Hubbard model. They observe the low energy spin excitations at the K point persist in the transition from an insulator to a metal. This result is consistent with nuclear magnetic resonance observations on triangular compounds.
