@article{GMS2009, abstract = {We report the existence, and study mobility and interactions of gap polariton solitons in a microcavity with a periodic potential, where the light field is strongly coupled to excitons. Gap solitons are formed due to the interplay between the repulsive exciton-exciton interaction and cavity dispersion. The analysis is carried out in an analytical form, using the coupled-mode (CM) approximation, and also by means of numerical methods.}, author = {Gorbach, A V and Malomed, B A and Skryabin, D V}, journal = {Physics Letters A}, number = {34}, pages = {3024--3027}, title = {{Gap polariton solitons}}, volume = {373}, year = {2009} }
