    "abstract": "The Qprop package is presented. Qprop has been developed to study laser-atom\ninteraction in the nonperturbative regime where nonlinear phenomena such as\nabove-threshold ionization, high order harmonic generation, and dynamic\nstabilization are known to occur. In the nonrelativistic regime and within the\nsingle active electron approximation, these phenomena can be studied with Qprop\nin the most rigorous way by solving the time-dependent Schr\\\"odinger equation\nin three spatial dimensions. Because Qprop is optimized for the study of\nquantum systems that are spherically symmetric in their initial, unperturbed\nconfiguration, all wavefunctions are expanded in spherical harmonics.\nTime-propagation of the wavefunctions is performed using a split-operator\napproach. Photoelectron spectra are calculated employing a window-operator\ntechnique. Besides the solution of the time-dependent Schr\\\"odinger equation in\nsingle active electron approximation, Qprop allows to study many-electron\nsystems via the solution of the time-dependent Kohn-Sham equations.",
