semi-metal state<br />
In Hartree-Fock, one f<strong>in</strong>ds a semi-metallic<br />
solution <strong>in</strong> <strong>the</strong> cubic system<br />
This corresponds to <strong>the</strong> bond-centered SDW,<br />
<strong>and</strong> essentially electrons <strong>of</strong> one <strong>sp<strong>in</strong></strong><br />
polarization are conf<strong>in</strong>ed to a pair <strong>of</strong><br />
parallel planes<br />
This forms a honeycomb lattice<br />
