Endohedral fullerenes (A@C60), fullerenes with an encaged atom/molecule (A), are capable of controlling resonant HHG, when driven by a strong laser pulse [1]. Being giant molecules, the multi-center nature of HHG arises naturally [2-3]. Thus, elliptical HHG could be generated even with a linearly polarized ultrafast laser pulse [4]. Elliptical HHG in fullerenes/carbon clusters are found to be very rich owing to the complex nature of these molecular targets [5]. Employing the molecular SFA, we aim at evaluating the ellipticity dependence of HHG from A@C60 under linearly and elliptically polarized ultrafast laser pulses. Further, to account for electron correlations in the HHG spectrum [6], we perform TDDFT simulations. 1. P. V. Redkin, M. B. Danailov, and R. A. Ganeev, Phys. Rev. A 84, 013407 (2011). 2. M. F.
