Levitated nano-trampoline resonators for magnetic field sensing
Xianfeng Chen, Nirmala Raj, Matthew R. Chua +7
Levitated systems and high- membrane nanomechanical resonators have achieved exceptional sensitivity in precision sensing, but functionalizing such resonators for practical appl…
Experimental Quantification of Nonlinear Mode Coupling in Nanomechanical Resonators using Multi-tone Excitation
Chris F. D. Wattjes, Zichao Li, Minxing Xu +3
Nonlinear modal interactions in resonant systems govern a wide range of phenomena, with broad relevance across modern physics and engineering. Yet, experimentally determining the s…
High-Strength Amorphous Silicon Carbide for Nanomechanics
Minxing Xu, Dongil Shin, Paolo M. Sberna +4
For decades, mechanical resonators with high sensitivity have been realized using thin-film materials under high tensile loads. Although there have been remarkable strides in achie…
High-Resolution Casimir Force Sensing Across a Superconducting Transition
Minxing Xu, Robbie J. G. Elbertse, Ata KeÅkekler +4
The Casimir effect and superconductivity are foundational quantum phenomena whose interplay is an open question in physics, with significant implications for electron physics, quan…
Cascade of Modal Interactions in Nanomechanical Resonators with Soft Clamping
Zichao Li, Minxing Xu, Richard A. Norte +3
We uncover a chain of nonlinear modal interactions in softly clamped nanostring resonators. The process involves the sequential coupling of five mechanical modes, during frequency…
