    "abstract": "We consider a two-photon transition in a specific ladder system driven by a\nchirped laser pulse. In the weak field limit, we find that the excited state\nprobability amplitude arises due to interference of multiple quantum paths\nwhich are weighted by quadratic phase factors. The excited state population has\nthe form of a Gauss sum which plays a prominent role in number theory.",
