Competing Phases in Correlated Electron Systems with Frus...
Sahebsara, Peyman
The variational cluster approximation, based on the self-energy functional theory for electrons, is one of the quantum cluster methods, we introduced to investigate the broken symmetry states of strongly correlated systems. Layered organic compounds, in which dimers of organic molecules form an anisotropic triangular lattice, are among materials that show frustration. We discuss the two-dimensional one-band Hubbard model used for studying thes...
