Effect of material stiffness on intermodulation response in dynamic atomic force microscopy
Daniel Platz, Daniel Forchheimer, Erik A. Tholén +2
We perform simulations and experiments on an oscillating atomic force microscope cantilever approaching a surface, where the intermodulation response of the cantilever driven with…
The Intermodulation Lockin Analyzer
Erik A. Tholen, Daniel Platz, Daniel Forchheimer +4
Nonlinear systems can be probed by driving them with two or more pure tones while measuring the intermodulation products of the drive tones in the response. We describe a digital l…
Phase imaging with intermodulation atomic force microscopy
Daniel Platz, Erik A. Tholen, Carsten Hutter +2
Intermodulation atomic force microscopy (IMAFM) is a dynamic mode of atomic force microscopy (AFM) with two-tone excitation. The oscillating AFM cantilever in close proximity to a…
Reconstructing nonlinearities with intermodulation spectroscopy
Carsten Hutter, Daniel Platz, E. A. Tholen +2
We describe a method of analysis which allows for reconstructing the nonlinear disturbance of a high Q harmonic oscillator. When the oscillator is driven with two or more frequenci…
Parametric amplification with weak-link nonlinearity in superconducting microresonators
Erik A. Tholen, Adem Ergul, Kai Stannigel +2
Nonlinear kinetic inductance in a high Q superconducting coplanar waveguide microresonator can cause a bifurcation of the resonance curve. Near the critical pumping power and frequ…
Dissipation in circuit quantum electrodynamics: lasing and cooling of a low-frequency oscillator
Julian Hauss, Arkady Fedorov, Stephan André +6
Superconducting qubits coupled to electric or nanomechanical resonators display effects previously studied in quantum electrodynamics (QED) and extensions thereof. Here we study a…
