Phonons in an Inhomogeneous Continuum: Vibrations of an Embedded Nanoparticle
arXiv:cond-mat/0310099 · doi:10.1103/PhysRevB.69.094305
Abstract
The spectrum of acoustic vibrational modes of an inhomogeneous elastic continuum are analyzed with application to a spherical nanoparticle embedded in an infinite glass block. The relationship of these modes to the discrete vibrational spectrum of a free sphere is studied. The vibrational modes of a sphere with a fixed surface are relevant in some situations. Comparisons are also made to calculations of mode frequency and damping based on complex valued frequency.
