Optical lattices are very useful systems for quantum simulation and studying quantum many body systems.  In their excellently named manuscript: Shaken not stirred: creating exotic angular momentum states by shaking an optical lattice, Kiely et al propose a method to produce higher orbital states of cold atoms in an optical lattice.  Their method involves ‘shaking’ the lattice (changing the positions of the minima in the trap).  The image below shows the target state of their method, with the atoms in an anti-ferromagnetic arrangment in the lattice.
