Based on the Tavis–Cummings model, the entanglement dynamics between two atoms coupled nonsymmetrically to a single-mode $$l$$l-photon coherent field is investigated through analytical and numerical method. It is found that nonsymmetry plays a critical role in entangling two atoms and can lead to the sudden birth of entanglement, compared with a sudden death. Moreover, influences of coherent intensity, atom/field resonance order and squeezing order of coherent field upon entanglement evolution are also explored.
