Superfluidity and solid orders in two-component Bose gas with dipolar interactions in an optical lattice
Y. Kuno, K. Suzuki, I. Ichinose
In this paper, we study an extended bosonic t-J model in an optical lattice, which describes two-component hard-core bosons with a nearest-neighbor (NN) pseudo-spin interaction, an…
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…
Finite-temperature phase diagram of two-component bosons in a cubic optical lattice: Three-dimensional t-J model of hard-core bosons
Y. Nakano, T. Ishima, N. Kobayashi +3
We study the three-dimensional bosonic t-J model, i.e., the t-J model of "bosonic electrons", at finite temperatures. This model describes the Heisenberg spin model…
Multi-Higgs U(1) Lattice Gauge Theory in Three Dimensions
Tomoyoshi Ono, Ikuo Ichinose, Tetsuo Matsui
We study the three-dimensional compact U(1) lattice gauge theory with Higgs fields numerically. This model is relevant to multi-component superconductors, antiferromagnetic spi…
Comment on ``Confinement of slave particles in U(1) gauge theories of strongly interacting electrons"
I. Ichinose, T. Matsui
In a recent Letter, Nayak argued that slave partices are always confined in gauge theories of strongly-correlated electron systems like the t-J model. The argument mostly relies on…
