Parametric gates and processes engineered from the perspective of the staticeffective Hamiltonian of a driven system are central to quantum technology.However, the perturbative expansions used to derive static effective models maynot be able to efficiently capture all the relevant physics of the originalsystem. In this work, we investigate the conditions for the validity of theusual low-order static effective Hamiltonian used to describe a Kerr oscillatorunder a squeezing drive. In this work, we exploit the opportunity provided bythis system, which is sufficiently simple to be built and operated in the lab,sufficiently complex to require modern calculation techniques for theexploration of nontrivial parameter regimes, and sufficiently rich to be offundamental and technological interest. We compare the low-order staticeffective states and energies with the exact Floquet states and quasi-energiesand determine the parameter regime where the descriptions agree. Our workbrings to light the physics that is left out by ordinary static effectivetreatments and that can be explored by state-of-the-art experiments.
