WebNov 13, 2011 · A photon is a packet of energy, which is the base of quantum mechanics. A phonon is the collective oscillation of several atoms. Both of these concepts are very important in physics. Photon theory is the underlying theory that most of the modern physics is dependent on. WebSep 7, 2024 · Figure 1: Collective motions called phonons (Public Domain; Sean Kelley via NIST) Quantum theory uses the concepts of phonons, which are “quasi-particles” with definite energies and directions of motion, to treat the vibrations. The concept of phonon is analogous with photons of the electromagnetic wave. fixed income securities tuckman pdf
