    The authors use the Crank-Nicolson scheme in time and the finite element method in space to solve a class of nonlinear Riesz space-fractional Schrödinger equations. Using a Brouwer fixed point theorem and a fractional Gagliardo-Nirenberg inequality, unique solvability of fully discrete systems is proved. The conservation and convergence properties of the semi-discrete scheme and the fully discrete one are analyzed. A linearized iterative finite element algorithm is introduced and some numerical examples are given to support the theoretical results.
