title = "Experimental study of thermal noise caused by an inhomogeneously distributed loss",
abstract = "The thermal fluctuation of a mechanical system with an inhomogeneously distributed loss was measured to prove the invalidity of the normal-mode expansion method which is commonly used to calculate the thermal noise of mechanical oscillators. The measured spectrum is inconsistent with the modal expansion model, while they agree well with an evaluation obtained by applying the fluctuation-dissipation theorem to the measured mechanical response. These are the first experimental results which show that mode expansion is invalid.",
