Fluctuations of one of the components are often squeezed, whereas fluctutions of the other component, which is shifted in phase by π/2, are increased. Squeezing is a multi-faceted phenomenon, it attracts much attention from the perspective of high-precision measurements. Here we demonstrate a new and hitherto unappreciated side of squeezing: its direct manifestation in the spectra of driven vibrational systems. With a weakly damped nanomechanical resonator, we study the spectrum of thermal fluctuations of a resonantly driven nonlinear mode. In the attained sideband-resolved regime, we show that the asymmetry of the spectrum directly characterizes the squeezing. This opens a way to deduce squeezing of thermal fluctuations in strongly underdamped resonators, for which a direct determination by a standard homodyne measurement is impeded by frequency fluctuations. The experimental and theoretical results are in excellent agreement. We further extend the theory to also describe the spectral manifestation of squeezing of quantum fluctuations.</dcterms:abstract> <dc:creator>Seitner, Maximilian J.</dc:creator> <dc:creator>Weig, Eva M.</dc:creator> <dc:contributor>Seitner, Maximilian J.</dc:contributor> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/49405/1/Huber_2-18ck63n8imlxn8.pdf"/> <dc:creator>Dykman, Mark I.</dc:creator> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by/4.0/"/> <dc:creator>Rastelli, Gianluca</dc:creator> <dc:contributor>Huber, Jana S.</dc:contributor> <dc:contributor>Weig, Eva M.</dc:contributor> <dc:contributor>Rastelli, Gianluca</dc:contributor> <dcterms:title>Spectral evidence of squeezing of a weakly damped driven nanomechanical mode</dcterms:title> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dc:language>eng</dc:language> <dc:contributor>Belzig, Wolfgang</dc:contributor> <dc:creator>Belzig, Wolfgang</dc:creator> </rdf:Description> </rdf:RDF>
