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…
Superfluid, Supersolid and Checkerboard Solid in Two-Component Bosons in an Optical Lattice: Study by Means of Gross-Pitaevskii Theory and Monte-Carlo Simulations
Y. Kuno, K. Suzuki, I. Ichinose
The bosonic t-J model is a strong-on-site repulsion limit of the two-component Bose-Hubbard model and is expected to be realized by experiments of cold atoms in an optical lattice.…
Effective field theory for two-species bosons in an optical lattice: Multiple order, the Nambu-Goldstone bosons, the Higgs mode and vortex lattice
Y. Kuno, K. Suzuki, I. Ichinose
In the previous papers, we studied the bosonic t-J mode and derived an effective field theory, which is a kind of quantum XY model. The bosonic t-J model is expected to be realized…
Numerical Studies of Fano Resonance in Quantum dots Embedded in AB Rings
Akiko Ueda, Ikuo Baba, Keita Suzuki +1
The Fano resonance in quantum dots embedded in Aharonov-Bohm rings is examined theoretically, using two models of non-interacting electrons. The first model yields an analytical ex…
