Show affiliationsIn this paper, an approximate analytic solution is presented for describing a fundamental soliton in a nonlocal medium with exponential response nonlinearity, by employing a variational approach. By comparing it with the exact solution obtained under special conditions and a numerical solution, it is shown that this approximate analytic solution can provide a good description of the behavior of a fundamental soliton for a wide range of parameters, and in particular for a small energy flow.
