Abstract: A spin-wave (SW) approach for hard-core bosons is presented to treat the problem of two dimensional boson localization in a random potential.After a short review of the method to compute 1/S-corrected observables, the case of random on-site energy is discussed.Whereas the mean-field solution does not display a Bose glass (BG) phase, 1/S corrections do capture BG physics.In particular, the localization of SW excitations is discussed through the inverse participation ratio.
