Quantum phases of the Bose-Hubbard model in optical superlattices
In this paper, we analyze the quantum phases of multiple component Bose-Hubbard model in optical superlattices, using a mean-field method, the decoupling approximation. We find that the phase diagrams exhibit complected patterns and regions with various Charge Density Wave (CDW) for both one- and two- component cases. We also analyze …
