Microwave optomechanical measurement of non-metallized SiN strings at mK temperatures
Sumit Kumar, Yannick Klaß, Baptiste Alperin +5
The mechanical properties of amorphous materials (glasses) at low temperatures are dominated by effects of low energy excitations that are thought to be atomic-scale tunneling two…
Resonant nonlinear response of a nanomechanical system with broken symmetry
J. S. Ochs, G. Rastelli, M. Seitner +2
We study the response of a weakly damped vibrational mode of a nanostring resonator to a moderately strong resonant driving force. Because of the geometry of the experiment, the st…
Room temperature cavity electromechanics in the sideband-resolved regime
Anh Tuan Le, Alexandre Brieusssel, Eva Maria Weig
We demonstrate a sideband-resolved cavity electromechanical system operating at room temperature. The mechanical resonator, a strongly pre-stressed silicon nitride string, is diele…
Universal length dependence of tensile stress in nanomechanical string resonators
Maximilian Bückle, Yannick S. Klaß, Felix B. Nägele +2
We investigate the tensile stress in freely suspended nanomechanical string resonators, and observe a material-independent dependence on the resonator length. We compare strongly s…
Amplification and spectral evidence of squeezing in the response of a strongly driven nanoresonator to a probe field
J. S. Ochs, M. Seitner, M. I. Dykman +1
Because of their small decay rates, nanomechanical modes enable studying strongly nonlinear phenomena for a moderately strong resonant driving. Here we study the response of a driv…
Tuning the nonlinear dispersive coupling of nanomechanical string resonators
K. Gajo, G. Rastelli, E. M. Weig
We investigate nonlinear dispersive mode coupling between the flexural in- and out-of-plane modes of two doubly clamped, nanomechanical silicon nitride string resonators. As the am…
