WebIf one is interested in the photon particle/wave duality one has to look at a single photon at the time. In the two slit experiment single photons build up the same interference pattern … WebMay 13, 2016 · The concept of phonons was introduced by Tamm 1 in 1930 through an observation of the particle-like energetics of atomic vibrations in a crystal, similar to the wave–particle duality in quantum ...
WebSep 20, 2024 · Planck's investigation of the emission spectra of hot objects and the subsequent studies into the photoelectric effect had proven that light was capable of behaving both as a wave and as a particle. It seemed reasonable to wonder if electrons could also have a dual wave-particle nature. WebMay 11, 2011 · I fully understand the wave-particle duality of photon's and electrons and the like, but I don't see how this works with phonon's. From my rather basic understanding (all from before I learned enough about QM to understand it), a phonon is the localised vibration of atoms through a solid that allows sound to occur.
The direction of the wave vector is the direction of the wave propagation and the phonon polarization vector gives the direction in which the atoms vibrate. Actually, in general, the wave velocity in a crystal is different for different directions of k. In other words, most crystals are anisotropic for phonon proagation. See more 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 … 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. … 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 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 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. See more By analogy to photons and matter waves, phonons have been treated with wavevector k as though it has a momentum ħk; … See more The phonon Hamiltonian is given by $${\displaystyle {\mathcal {H}}={\tfrac {1}{2}}\sum _{\alpha }\left(p_{\alpha }^{2}+\omega _{\alpha }^{2}q_{\alpha }^{2}-\hbar \omega _{\alpha }\right)}$$ In terms of the creation and annihilation operators, … See more WebThe relationship between wave-particle duality measures ( P and V) and source impurity (μ s) given in Eq. 13 led to a new interpretation of the wave-particle duality because the source purity of quantons can limit the totality of complementarity between the wave-like and particle-like behaviors of quantons.

WebThe concept of wave-particle duality says that light has properties of both a particle and a wave. It also says that small particles such as electrons behave like both waves and particles. This idea was proposed by Louis de Broglie when he outlined the results of some experiments in his PhD thesis.
