Abstract
We study the dynamics of solitons under the action of one-dimensional quasiperiodic lattice potentials, fractional diffraction, and nonlinearity. The formation and stability of the solitons are investigated in the framework of the fractional nonlinear Schrödinger equation. By means of variational and numerical methods, we identify conditions under which stable solitons emerge, stressing the effect of fractional diffraction on soliton properties. The reported findings contribute to understanding the soliton behavior in complex media, with implications for topological photonics and matter-wave dynamics in lattice potentials.
