    "abstract": "A calculation valid to all orders in the nuclear-strength parameter is\npresented for the two-loop Lamb shift, notably for the two-loop self-energy\ncorrection, to the 2p-2s transition energies in heavy Li-like ions. The\ncalculation removes the largest theoretical uncertainty for these transitions\nand yields the first experimental identification of two-loop QED effects in the\nregion of the strong binding field.",
