Crystal, Superfluids, Supersolid and Hetero-Structure in System of Two-Component Strongly-Correlated Bosons in a Cubic Optical Lattice
Ikuo Ichinose, Takumi Ishima, Naohiro Kobayashi +1
In the present paper, we study finite-temperature phase structure of two-component hard-core bosons in a cubic optical lattice. The system that we study in the present paper is an…
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…
Affleck-Dine leptogenesis in the radiative neutrino mass model
H. Higashi, T. Ishima, D. Suematsu
Radiative neutrino mass models have interesting features, which make it possible to relate neutrino masses to the existence of dark matter. However, the explanation of the baryon n…
Antiferromagnetic Order and Bose-Einstein Condensation in Strongly-Correlated Cold-Atom Systems: Bosonic t-J Model in the Double-CP^1 Representation
Yuki Nakano, Takumi Ishima, Naohiro 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 a system of cold bosonic atoms with two sp…
