Effective field theories for two-component repulsive bosons on lattice and their phase diagrams
Y. Kuno, K. Kataoka, I. Ichinose
In this paper, we consider the bosonic t-J model, which describes two-component hard-core bosons with a nearest-neighbor (NN) pseudo-spin interaction and a NN hopping. To study pha…

Phase Structure of Repulsive Hard-Core Bosons in a Stacked Triangular Lattice
H. Ozawa, I. Ichinose
In this paper, we study phase structure of a system of hard-core bosons with a nearest-neighbor (NN) repulsive interaction in a stacked triangular lattice. Hamiltonian of the syste…
