The exact solution of a fragmented Bose-Hubbard model and twisted models
Gilberto N. Santos Filho
We present the exact solution of a family of fragmented Bose-Hubbard models and represent the models as graphs with the condensates in the vertices. The models are solved by the al…

The exact solution of a generalized Bose-Hubbard model
Gilberto N. Santos Filho
I present the exact solution of a family of fragmented Bose-Hubbard models and represent the models as graphs in one-dimension, two-dimensions and three-dimensions with the condens…

Currents algebra for an atom-molecule Bose-Einstein condensate model
Gilberto N. Santos Filho
I present an interconversion currents algebra for an atom-molecule Bose-Einstein condensate model and use it to get the quantum dynamics of the currents. For different choices of t…
