What the study reports
In a quartz phononic crystal, microwave measurement drives microscopic two-level defects away from equilibrium. The reported amplitude-dependent resonance combines frequency shifts and dissipation, with either hardening or softening. A thermal-conductance model coupled to defect theory reproduces the measured power dependence. [1]
What this does not establish
The publisher abstract was assessed; subscription methods were not reviewed. The findings concern millikelvin operation and do not establish comparable behavior in room-temperature mechanical lattices.
Our engineering reading
Our interpretation is that measurement-induced heating deserves attention when assigning nonlinear response or coherence limits to the structure itself.
Editorial interpretation; not an additional measured result.Readout-induced heating of defects as a source of mechanical nonlinearity
