• Abstract summary: We show that the time evolution of a parametrically driven dissipative quantum oscillator has a strong connection with the classical damped Mathieu equation. We obtain a closed relationship between the localization of the Wigner function and the stability of the damped Mathieu equation.

• Abstract: We study the dissipative dynamics of a single quantum harmonic oscillator subjected to a parametric driving with in an effective Hamiltonian approach. Using Liouville von Neumann approach, we show that the time evolution of a parametrically driven dissipative quantum oscillator has a strong connection with the classical damped Mathieu equation. Based on the numerical analysis of the Monodromy matrix, we demonstrate that the dynamical instability generated by the parametric driving are reduced by the effect of dissipation. Further, we obtain a closed relationship between the localization of the Wigner function and the stability of the damped Mathieu equation.

The pictorial structure associated with each diagram corresponds directly to a Hamiltonian term, the prefactor of which involves a simple counting of topologically equivalent diagrams. Our method establishes the foundation of the dynamic control of quantum systems with the precision needed for future quantum machines.

We analyze the second-order topological corner modes that arise when an in-plane magnetic field is applied. We show that oscillations persist even in the adiabatic phase because of a frequency independent coupling between zero modes and excited states.

  The squeezing effect arises in the interacting qubit-oscillator system. Based on the generalized rotating wave approximation, the approximate energy spectrum is compared with the numerically determined spectrum of the Hamiltonian. It is shown that the squeezing produced in the Rabi model can be enhanced substantially in the presence of a parametric nonlinear term.
