Exact number conserving phase-space dynamics of the M-site Bose-Hubbard model
F. Trimborn, D. Witthaut, H. J. Korsch
The dynamics of M-site, N-particle Bose-Hubbard systems is described in quantum phase space constructed in terms of generalized SU(M) coherent states. These states have a special s…

Beyond mean-field dynamics of small Bose-Hubbard systems based on the number-conserving phase space approach
F. Trimborn, D. Witthaut, H. J. Korsch
The number-conserving quantum phase space description of the Bose-Hubbard model is discussed for the illustrative case of two and three modes, as well as the generalization of the…
