Exact analytical solutions describing spatially localized self-trapped modes in highly nonlocal nonlinear media are presented. We formulate the model in a coordinate-free form and show that it allows us to obtain useful closed-form expressions for a large variety of mode structures and their interactions in a highly nonlocal nonlinear medium. © 2007 The American Physical Society.
