Comment on recent Physical Review Letter by Gaidarzhy, et al. "Evidence for quantized displacement in macroscopic nanomechanical oscillator."
2005
In a recent letter, Gaidarzhy et al. claim to have observed evidence for quantized displacements of a nanomechanical oscillator. We contend that the evidence, analysis, claims, and conclusions presented are contrary to expectations from fundamentals of quantum mechanics and elasticity theory, and that the method used by the authors is unsuitable in principle to observe the quantized energy states of a nanomechanical structure.
