The UHF solution appears when the hopping integral t becomes small and leads to a spin density wave. The localization of the MOs leads to a and b atom centered orbitals, localized around odd and even labelled atoms respectively.

Superconductivity has also been found to coexist and compete with itinerant-electron antiferromagnetism (spin density waves) which has extensively reviewed by Gabovich et al. (2001). 

SC — superconducting, AFM — commensurate antifenomagnet structure, SDW — incommensurate antiferro-magnet order (spin density wave), WFM — weak ferromagnetism Tn — magnetic ordering temperature, Tc — superconducting transition temperature and N(Ep) —density of states at the Fermi level.

The collective behavior of condensed modulated structures like charge or spin density waves (CDWs/SDWs) [23, 22, 4], flux line lattices [2, 36] and Wigner crystals [4] in random environments has been the subject of detailed investigations since the early 1970s. These were motivated by the drastic influence...

The problem of anti ferromagnetic (AF) ordering in applied magnetic field observed at low temperatures in the high-T), cuprates from neutron scattering [1] (and supporting picture from STM measurements [2]) is intensively discussed now. This AF ordering (spin density wave (SDW)) is... 

Then, note also that recently it was introduced a concept of so-called hidden order in the cuprates (see, e.g. [16]). Such an order is attributed to d-density wave (DDW) order. However, in their statement the type of this DDW order is not concrete but it is only considered as competing (not vital) order for SC one, moreover it is considered as corresponding to the superconductivity with dx2 yi -wave pairing symmetry. As follows from above this concept may be described in terms of the (spin) density wave (S) (DW) with a dx2 y2 -wave symmetry accompanied by (charge) density wave (C)...
