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}…

Quantum Phase Transition in Lattice Model of Unconventional Superconductors
Kenji Sawamura, Yuki Moribe, Ikuo Ichinose
In this paper we shall introduce a lattice model of unconventional superconductors (SC) like d-wave SC in order to study quantum phase transition at vanishing temperature (). Fi…
