Abstract: We study how the bosonic atoms on the excited p-band of an optical latticeare coupled to the lowest s-band and the 2nd excited d-band. We find that insome parameter regimes the atom-atom interactions can cause a dynamicalinstability of the p-band atoms towards decay to the s- and d-bands.Furthermore, even when dynamical instability is not expected s- and d-bands canbecome substantially populated.
