Regulating atomic imbalance in double-well lattices
arXiv:0904.4612 · doi:10.1016/j.physleta.2008.11.067
Abstract
An insulating optical lattice with double-well sites is considered. In the case of the unity filling factor, an effective Hamiltonian in the pseudospin representation is derived. A method is suggested for manipulating the properties of the system by varying the shape of the double-well potential. In particular, it is shown that the atomic imbalance can be varied at will and a kind of the Morse-alphabet sequences can be created.
