• Authors: Ines C. Rodrigues, Gary A. Steele, Daniel Bothner,
• Abstract summary: We show a microwave mode in a superconducting LC circuit that mimics the dynamics of a negative mass oscillator. We demonstrate that the effective negative mass dynamics lead to an inversion of dynamical backaction and to sideband-cooling of the low-frequency circuit by a blue-detuned pump field.

• Abstract: Harmonic oscillators belong to the most fundamental concepts in physics and are central to many current research fields such as circuit QED, cavity optomechanics and photon-pressure systems. Here, we engineer a microwave mode in a superconducting LC circuit that mimics the dynamics of a negative mass oscillator, and couple it via photon-pressure to a second low-frequency circuit. We demonstrate that the effective negative mass dynamics lead to an inversion of dynamical backaction and to sideband-cooling of the low-frequency circuit by a blue-detuned pump field, which can be intuitively understood by the inverted energy ladder of a negative mass oscillator.

  We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide. When the frequency of this motion approaches twice the qubit resonance frequency, it induces parametric generation of photons and excitation of the qubits. We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

  We realize the mechanical dynamical Casimir effect (DCE) in a hybrid optomechanical system. The mechanical energy is found to be directly converted into the output photons through a three-wave-mixing mechanism. It is found that the mechanical frequency can be about two orders of magnitude smaller than the output photons.

• Single-photon induced instabilities in a cavity electromechanical device [0.0]
  nonlinear radiation-pressure interaction in Cavity-electromechanical systems could result in an unstable response of the mechanical resonator. By using polariton modes formed by a strongly coupled flux-tunable transmon and a microwave cavity, here we demonstrate an electromechanical device and achieve a single-photon coupling rate. Such an improvement in the single-photon coupling rate and the observations of microwave frequency combs at single-photon levels may have applications in the quantum control of the motional states and critical parametric sensing.

  We propose a novel type of a Bose-Hubbard ladder model to study the physics of dynamical gauge potentials. A steady-state atomic motion along the legs of the ladder leads either to a pure chiral current, or generates simultaneously chiral and particle currents. An electromotive force is induced in this dynamical regime as expected from an interpretation based on Faraday's law of induction for the time-dependent synthetic magnetic flux.
