• Abstract: In this paper, we present a rigorous analysis of symmetry and underlying physics of the nonlinear two-mode system driven by a harmonic mixing field, by means of multiple scale asymptotic analysis method. The effective description in the framework of the second-order perturbative theory provides an accurate picture for understanding the Floquet eigenspectrum and dynamical features of the nonlinear two-mode system, showing full agreement with the prediction of symmetry considerations. We find that two types of symmetries play significant role in the dynamical features of this model, the mechanism behind which can be interpreted in terms of the effective description. The results are of relevance for the phase control of the atomic localization in Bose-Einstein condensates or switch of the optical signals in nonlinear mediums.

  This work explores the possibility of creating and controlling unconventional nonlinearities by periodic driving. By means of a parent quantum many-body description, we demonstrate that such driven systems are well captured by an effective NLSE. We analyze these intriguing properties both in the weakly-interacting (mean-field) regime, captured by the effective NLSE, and in the strongly-correlated quantum regime.

  We compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models.

We show the geometric phase is robust, exhibiting a vanishing correction under a non-unitary evolution.
