- Abstract summary: We provide a recipe for the choice of the parameters that ensures a regular dynamical behavior independently of the driving strength.
We show that this suppression of chaotic phenomena is compatible with a strong quantum nonlinear effect reflected by the confinement rate in the degenerate manifold spanned by stable subharmonic orbits.

- Abstract: Driven quantum nonlinear oscillators, while essential for quantum
technologies, are generally prone to complex chaotic dynamics that fall beyond
the reach of perturbative analysis. By focusing on subharmonic bifurcations of
a harmonically driven oscillator, we provide a recipe for the choice of the
oscillator's parameters that ensures a regular dynamical behavior independently
of the driving strength. We show that this suppression of chaotic phenomena is
compatible with a strong quantum nonlinear effect reflected by the confinement
rate in the degenerate manifold spanned by stable subharmonic orbits.
