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 spinon (Schwinger boson) field and a Higgs field. It is a bosonic - model in slave-particle representatio…

Four-dimensional CP U(1) lattice gauge theory for 3D antiferromagnets: Phase structure, gauge bosons and spin liquid

Kenji Sawamura, Takashi Hiramatsu, Katsuhiro Ozaki +2

In this paper we study the lattice CP model in (3+1) dimensions coupled with a dynamical compact U(1) gauge field. This model is an effective field theory of the $s={1 \over 2}…

Higgs mechanism and superconductivity in U(1) lattice gauge theory with dual gauge fields

Tomoyoshi Ono, Yuki Moribe, Shunsuke Takashima +3

We introduce a U(1) lattice gauge theory with dual gauge fields and study its phase structure. This system is motivated by unconventional superconductors like extended s-wave and d…
