Flow representation of the Bose-Hubbard Hamiltonian: General case

Kazuyuki Fujii, Tatsuo Suzuki

Research output: Contribution to journalArticlepeer-review


In this paper the explicit flow representation to the Bose-Hubbard Hamiltonian is given in the general case. This representation may be useful in creating cat states for the system of atoms trapped in the optical ring.
