The existence is determined by using a minimizing constrained problem in the complex setting and it is showed that the corresponding real solution is always positive. The orbital stability is proved by combining some tools regarding the oscillation theorem for fractional Hill operators and the Vakhitov-Kolokolov condition, well known for Schrödinger equations. We then perform a numerical approach to generate the periodic standing wave solutions of the fNLS equation by using the Petviashvili's iteration method. We also investigate the Vakhitov-Kolokolov condition numerically which cannot be obtained analytically for some values of the order of the fractional derivative.engrestrictedAccessarticle34126329100087052810000610.1016/j.jde.2022.09.015Existence and uniqueness of minimizersFractional Schrödinger equationOrbital stabilitySmall-amplitude periodic waves2-s2.0-85138500911
