Green's functions and energy eigenvalues for delta-perturbed space-fractional quantum systems

Starting from the propagator, we introduced a time-ordered perturbation expansion and employed Wick rotation to obtain a general energy-dependent Green's function expressions for space-fractional quantum systems with Dirac delta-function perturbation. We then obtained the Green's functions and equations for the bound state energies for the space-fractional Schrodinger equation with single and double Dirac delta well potentials and the delta-perturbed infinite well.
