    "abstract": "We use the dressed atom formalism to calculate the frequency shift in a\nhydrogen maser induced by applied radiation near the Zeeman frequency, and find\nexcellent agreement with a previous calculation made in the bare atom basis.\nThe maser oscillates on the Delta_F = 1, Delta_m_F = 0 hyperfine transition,\nwhile the applied field is swept through the F = 1, Delta_m_F = \\pm 1 Zeeman\nresonance. We determine the effect of the applied field on the Zeeman levels\nusing the dressed atom picture, and then calculate the maser frequency shift by\ncoupling the dressed states to the microwave cavity. Qualitatively, the\ndressed-atom analysis gives a new and simpler physical interpretation of this\ndouble resonance process, which has applications in precision hydrogen Zeeman\nspectroscopy, e.g., in fundamental symmetry tests.",
