Extracting higher-order nonlinearities in nanomechanical resonators using the backbone relation
Maria Kallergi, Daniel K. J. BoneÃ, Maximilian Seitner +2
Nanomechanical resonators are a powerful platform for studying nonlinear dynamics with high sensitivity and precision. We explore the nonlinear response of a high-Q nanomechanical…
Fundamental and second-subharmonic Autler-Townes splitting in classical systems
Ahmed A. Barakat, Avishek Chowdhury, Anh Tuan Le +1
The dynamic Stark effect and the Autler-Townes splitting (ATS) are hallmarks of driven two-level systems. We establish a direct correspondence between these quantum phenomena and t…
In-situ profiling of pressure-induced exciton traps in suspended MoS monolayers
Leonard Geilen, Lukas Schleicher, Alexander Musta +4
We demonstrate the in-situ read-out of the spatial profile of suspended MoS monolayers hosted on substrates with nano-structured holes. As the profiles are spatially bent, the…
Monolithic 4H-SiC nanomechanical resonators with high intrinsic quality factors
A. Hochreiter, P. Bredol, F. David +3
We present an extensive study of 4H-SiC nanomechanical resonators electrochemically etched out of a monocrystalline wafer. Combining piezo-driven interferometric determination of t…
