Abstract
We study how the bosonic atoms on the excited p-band of an optical lattice are coupled to the lowest s-band and the 2nd excited d-band. We find that in some parameter regimes the atom-atom interactions can cause a dynamical instability 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 can become substantially populated.
