Abstract
Section titled “Abstract”We study the coherent dynamics of a qubit excited by an amplitude-modulated\nelectromagnetic field under the Rabi resonance when the frequency of the\nlow-frequency modulation field matches the Rabi frequency in the high-frequency\nfield. Due to destructive interference of multiple photon processes at the\nultrastrong coupling between the qubit and the low-frequency driving field,\nRabi oscillations result exclusively from the Bloch-Siegert effect. It is\ndirectly observed in the time-resolved coherent dynamics as the Bloch-Siegert\noscillation. In this case, triplets in Fourier spectra of the coherent response\nare transformed into doublets with the splitting between the lines equal to\ntwice the Bloch-Siegert shift. These unusual properties are demonstrated in\nconditions of experiments with a nitrogen vacancy center in diamond.\n
