Abstract: In this work, the quantum dynamics of a lithium atom confined within a fullerene cage (Li@Cn) under the influence of a short laser pulses are investigated using a hybrid theoretical approach that combines advanced techniques with both numerical and analytical methods. A static Woods–Saxon potential is employed to model the effects of endohedral confinement, and an additional noncentral potential is proposed to account for the anisotropic interactions between the confined Li atom and the carbon cage. For the noncentral Li@Cn molecule under the influence of short laser pulse, the wave equation is solved using an innovative hybrid approach that combines the tridiagonal matrix method, the asymptotic iteration method, and the Runge–Kutta–Fehlberg method, ensuring both numerical stability and analytical insight. The analysis of the system’s response to short laser pulses, enabled by our simulations and computational techniques, has made it possible to precisely track the electron dynamics. The key findings reveal that noncentral effects, fullerene confinement, and laser parameters (frequency and strength) exert significant control over the magnetic impulse characteristics arising from magnetic moments. Detailed analyses demonstrate how symmetry breaking modifies the nature of the magnetic impulse, offering tunability through external laser control. This work provides: (i) a computationally efficient framework for modeling anisotropic endohedral systems, (ii) quantitative predictions of laser pulse-induced magnetic responses in confined atomic systems, and (iii) fundamental insights into the manipulation of quantum-confined particles through the combination of geometric and dynamic control. The results are significant for the development of fullerene-based quantum materials with customizable electromagnetic properties.
