Abstract: | Exact solutions of Gaussian solitons in nonlinear media with a
Gaussian nonlocal response are obtained. Using the variational
approach, we obtain the approximate solutions of such solitons when
the degree of the nonlocality is arbitrary. Specifically, we study
the conditions for Gaussian solitons that propagate in weakly
and highly nonlocal media. We also compare the variational result
with the known exact solutions for weakly and highly nonlocal media. |
