Magnetic order, Bose-Einstein condensation, and superfluidity in a bosonic t-J model of CP^1 spinons and doped Higgs holons

Koji Aoki, Kazuhiko Sakakibara, Ikuo Ichinose +1

We study the three-dimensional U(1) lattice gauge theory of a CP${}^1$ spinon (Schwinger boson) field and a Higgs field. It is a bosonic $t$-$J$ model in slave-particle representatio…
