Abstract

fetched live from OpenAlex

Ultrasensitive mechanical probes are central to many nanoscale sensing and transduction protocols. Membrane phononic resonators patterned in silicon nitride under tension allow for precise engineering of both the mechanical mode spectrum and mechanical dissipation. The authors present a paradigm for the geometric design and description of phononic crystals based on geometric mass contrast. Characterization of a variety of devices at ambient and cryogenic temperatures identify device designs with low-mass, low-dissipation mechanical modes. These design principles can be readily applied to optomechanical devices for tomorrow's ultrasensitive force probes.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
