Abstract: Calculations of the two-loop electron self-energy for the n = 1 and n = 2 states of hydrogen-like ions are reported, performed to all orders in the nuclear binding strength parameter Z α (where Z is the nuclear charge number and α is the fine structure constant). The presented approach features an accelerated convergence of the partial-wave expansion and allows calculations to be accomplished for nuclear charges lower than previously possible and with a higher numerical accuracy.
