In particular, the three-body Floquet quasi-energy spectra are mapped out as a function of the driving amplitude and oscillation frequency of the interactions.
At low oscillation frequencies, we observe that dressed Efimov states emerge in different Floquet manifolds exhibiting a modified lifetime with respect to the undriven three-body system.
For intermediate and large oscillation frequencies, the dressed Efimov states strongly couple with the two- and three-body descritized continua yielding enhanced lifetimes that can be manipulated by adjusting the driving amplitude of the interactions.
Furthermore, by utilizing the hyperspherical potential curves, the phsyical origin of these admixed states is interpreted in terms of shape or Fano-Feshbach resonant scenarios.
