Abstract
In this paper, we are concerned with the explicit analytic solutions for the focusing and defocusing space shifted nonlocal nonlinear Schrödinger (NLS) equation introduced by Ablowitz and Musskimani (Phys Lett A 409:127516, 2021). The nonsingular N-soliton solutions of the defocusing space shifted nonlocal NLS equation are obtained, while the multi-rogue wave solutions are constructed for focusing space shifted nonlocal NLS equation by Darboux transformation. The asymptotic analysis of the soliton solutions is investigated theoretically and numerically. The dynamic features of first-, second-order RW solutions are analysed explicitly. It shows that the space shift \(x_0\) reveals more general dynamic behaviors in the space shifted nonlocal NLS equation.
