Different roles of Zn${}^{2+}$ and Li${}^{+}$ impurities in the CuO${}_2$ plane in undoped cuprate compounds

Jia-Wei Mei

A planar Mott insulator with easy plane Néel order can be mapped onto a Gutzwiller-projected spin Hall state. The in-plane substitution of Zn${}^{2+}$ and Li${}^{+}$ for Cu${}^{2+}$ brin…
