Introduction to Photonic Crystals: Bloch’s Theorem, Band …

In physics, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids. A type of quasiparticle, a phonon is an excited state in the quantum mechanical quantization of the modes of vibrations for elastic structures of … See more A phonon is the quantum mechanical description of an elementary vibrational motion in which a lattice of atoms or molecules uniformly oscillates at a single frequency. In classical mechanics this designates a See more The equations in this section do not use axioms of quantum mechanics but instead use relations for which there exists a direct correspondence in classical mechanics. For example: a rigid regular, crystalline (not amorphous) … See more By analogy to photons and matter waves, phonons have been treated with wavevector k as though it has a momentum ħk; however, this is not strictly correct, because ħk … See more The phonon Hamiltonian is given by In terms of the creation and annihilation operators, these are given by See more Solids with more than one atom in the smallest unit cell exhibit two types of phonons: acoustic phonons and optical phonons. Acoustic phonons are coherent movements of atoms of the lattice out of their equilibrium … See more The thermodynamic properties of a solid are directly related to its phonon structure. The entire set of all possible phonons that are described by the phonon dispersion relations combine in … See more As well as photons, phonons can interact via parametric down conversion and form squeezed coherent states. See more WebDec 1, 2005 · Phononic crystals make use of the fundamental properties of waves, such as scattering and interference, to create “band gaps” – ranges of wavelength or frequency within which waves cannot propagate through the structure. http://ab-initio.mit.edu/photons/tutorial/photonic-intro.pdf citation of a person
