Phonon wave particle duality
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 classical concepts "particle" or "wave" to fully describe the behaviour of quantum-scale objects. As Albert Einstein wrote:. It seems as though we must use sometimes the one … WebMar 7, 2024 · $\begingroup$ The cavity is not empty, it contains a photon . The photons existence in the cavity changes the energy levels of the highly excited Rydberg atom,. The authors claim it is by a superposition of wavefunctions thus no changes in energy for the photon, Similar to a monochromatic laser beam the photons are in superposition adding …
