Z(2) Gauge Neural Network and its Phase Structure
Yusuke Takafuji, Yuki Nakano, Tetsuo Matsui
We study general phase structures of neural-network models that have Z(2) local gauge symmetry. The Z(2) spin variable Si = \pm1 on the i-th site describes a neuron state as in the…
Finite-temperature phase structures of hard-core bosons in an optical lattice with an effective magnetic field
Yuki Nakano, Kenichi Kasamatsu, Tetsuo Matsui
We study finite-temperature phase structures of hard-core bosons in a two-dimensional optical lattice subject to an effective magnetic field by employing the gauged CP model. B…
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…
Vortex formation of a Bose-Einstein condensate in a rotating deep optical lattice
Akira Kato, Yuki Nakano, Kenichi Kasamatsu +1
We study the dynamics of vortex nucleation and lattice formation in a Bose--Einstein condensate in a rotating square optical lattice by numerical simulations of the Gross--Pitaevsk…
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…
