Inspired by Schaftingen [15], we develop a symmetric variational principle for the field equation involving a fractional Laplacians

$ \begin{equation*} \left\{ \begin{aligned} (-\Delta)^\alpha u+u& = f(u), x\in\mathbb{R}^N,\\ u(x)&\geq 0. \end{aligned} \right. \end{equation*} $

As an application, we prove the existence of symmetric ground states in the fractional Sobolev space

$ H^\alpha (\mathbb{R}^N) $

. These results improve some known ones in the literature. An example is also given to illustrate our results.

Keywords: Schrödinger equation, fractional Laplacian, ground state, rearrangement.
