Analysis
This paper presents experimental evidence of a novel thermally-driven nonlinearity in a micro-mechanical resonator. The nonlinearity arises from the interaction between the mechanical mode and two-level system defects. The study provides a theoretical framework to explain the observed behavior and identifies the mechanism limiting mechanical coherence. This research is significant because it explores the interplay between quantum defects and mechanical systems, potentially leading to new insights in quantum information processing and sensing.
Key Takeaways
- •Demonstrates a thermally-driven amplitude-frequency nonlinearity in a micro-mechanical resonator.
- •The nonlinearity is caused by the interaction between the mechanical mode and two-level system defects.
- •Provides a theoretical model to explain the observed behavior.
- •Identifies readout-enhanced relaxation damping as the primary mechanism limiting mechanical coherence.
