In this work we use the Lambda coupling scheme [3, 4, 5] with a control field containing two orthogonal standing waves (one of which is out-of-phase) to engineer a stwo-dimensional optical lattice with sub-wavelength characteristics by means of the geometric phase for the coherent dark state. By using two parameters: 1) the phase difference of the OOF standing wave, and 2) the amplitude ratio of the two orthogonal standing waves, one can control the tunneling parameters. The nonzero phase difference introduces a synthetic magnetic field which can be tuned to realize a weakly interacting tube model [6].
