Transport Properties of Superfluid Phonons in Neutron Stars
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 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 The phonon Hamiltonian is given by In terms of the creation and annihilation operators, … See more Solids with more than one atom in the smallest unit cell exhibit two types of phonons: acoustic phonons and optical phonons. 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 is not actually a physical momentum; it is called the crystal momentum or … See more As well as photons, phonons can interact via parametric down conversion and form squeezed coherent states. See more WebFestkörperphysik (Phononen und Elektronen im periodischen Potential, Bloch-Theorem, Hartree-Fock-Näherung, Dichtefunktional-Theorie, Elektron-Phonon-Wechselwirkung). Der erste Band ist bereits für Bachelor-Studierende geeignet, die sich über den Grundkurs in theoretischer Physik hinaus bereits in WebQuasi-Teilchen erfordern die Existenz eines externen Mediums oder Felder, Elementarteilchen hingegen nicht. Zum Beispiel benötigen Phononen einen Festkörper oder eine Flüssigkeit, um zu existieren (sie sind kollektive Moden der atomaren Gitterschwingung), ebenso benötigen Pionen ein Quark-Antiquark-Meer. green lake community center showers
