Making a group-theoretical analysis, we systematically reveal a variety of valence arrangements, including half-metallic charge-density-wave states. Quantum and thermal phase competition is numerically demonstrated with particular emphasis on doping-induced successive insulator-to-metal transitions with conductivity increasing stepwise.EDP Sciences, IOP Publishing and Società Italiana di FisicaJournal Articleapplication/pdfhttp://hdl.handle.net/2115/39291https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/39291/1/EPL87-1_17006.pdf0295-5075EPL871170062009-07enginfo:doi/10.1209/0295-5075/87/17006author
