Superimposing two optical lattice potentials differing in periodicity by a factor of two creates a superlattice structure. Together with two orthogonal lattices it provides a generic system to study isolated double well physics. By removing one of the orthogonal lattices one could extend the system from coupled quantum dots to coupled tubes, which allows us to extend the study of few-body physics to many-body physics. In addition, by adding another superlattice potential perpendicular to the first one, an array of plaquettes is created. In this talk we will discuss about recent progress in such a system.
