Abstract
A theory of quantization of intrinsic localized modes (ILM) in solids due to the hard nonlinearity is formulated within the rotating-wave approximation for the case of strong localization. An atom associated with the central position of the ILM and its nearest neighbors are treated as a defect in the corresponding linear lattice which is characterized by their mean-square displacements (MSD). A nonlinear eigenvalue problem for the ILM is thereby reduced to the linear one in which the MSD of the defect is determined in a self-consistent manner.
