title: (UHESILO) Ultra-High Efficiency Superconducting Isochronous Levitated Oscillator (High-Q, Nanowatt Sustain) v1.0

description: UHESILO proposes a compact, isochronous mechanical oscillator that maintains near-constant period over a wide amplitude range by shaping its potential toward a cycloid/brachistochrone profile. The device aims for ultra-high effective Q with nanowatt-scale sustain by combining (i) a low-loss potential “bowl,” (ii) levitation to minimize contact/friction, and (iii) rigorous electromagnetic hygiene (shielding, grounding, and low-noise drive). The goal is a robust physical timebase and force/inertial sensing platform that can operate continuously with minimal input power.

Why it matters.





Isochrony for timing: A shaped potential reduces amplitude-dependent period drift, improving timebase stability compared to simple harmonic systems.




High Q, low power: Levitation and loss budgeting target long ring-down times with nanowatt-class sustain, enabling portable or battery-friendly operation.




Metrology & sensing: With appropriate readout, UHESILO could serve as a testbed for precision force, acceleration, or gradient measurements.




Educational / demonstrative value: A tangible path to explore classical limits, dissipation channels, and control in precision mechanics.
