Exact solution of a generalized two-sites Bose-Hubbard model
Gilberto N. Santos Filho
I introduce a new parametrization of a bosonic Lax operator for the algebraic Bethe ansatz method with the -invariant -matrix and use it to present the exact solution of…
Current algebra for a generalized two-site Bose-Hubbard model
Gilberto N. Santos Filho
We present a current algebra for a generalized two-site Bose-Hubbard model and use it to get the quantum dynamics of the currents. For different choices of the Hamiltonian paramete…
Currents algebra for the two-sites Bose-Hubbard model
Gilberto N. Santos Filho
I present a currents algebra for the two-sites Bose-Hubbard model, generalize the Heisenberg equation of motion to write the second time derivative of the currents operators and us…
Exactly solvable models for multiatomic molecular Bose-Einstein condensates
G. Santos
I introduce two family of exactly solvable models for multiatomic hetero-nuclear and homo-nuclear molecular Bose-Einstein condensates through the algebraic Bethe ansatz method. The…
Quantum phase transitions in an interacting atom-molecule boson model
Gilberto Santos, Angela Foerster, Jon Links +2
We study the quantum phase transitions of a model that describes the interconversion of interacting bosonic atoms and molecules. Using a classical analysis, we identify a threshold…
