Phonon wave particle duality
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. WebWave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave. It expresses the inability of the …

WebJul 1, 2024 · It is commonplace to attribute this to particle impact. But since the in-flight photon also has a wave nature, we are stuck with the paradox of wave-particle duality. It is argued here that the photon’s wave nature is indisputable, but its particle nature is open to question. Photons deliver energy.

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.
