"Integrable regimes in nonlocal nonlinear optics"

Abstract: Nonlocal nonlinear optics (NNO) is one of the most
important developments in modern optics. In the recent years it was shown
that nonlocality plays a crucial role in the propagation of stable spatial
"solitons" in three dimensions. The problem of the integrability of
these kind of systems is still open, and, apart few (very interesting)
cases the main theoretical results on the behaviour of solutions are 
obtained numerically. Most of the models in NNO are based on a nonlocal
nonlinear Schrodinger (NNLS) type equation. The dispersionless limit of 
the NNLS equation is equivalent to the geometric optics limit. We analyze
in detail singular phase solutions and introduce a class of integrable 
nonlocal perturbations. We also  discuss the possibility to introduce 
wave(dispersive)-deformations for different nonlocal models.
