What Quasi-particle did Igor predict?
Leptons
Mesons
Gluons
Phonons
Answer
Phonons, as Igor predicted, are quanta of sound or vibrational energy. They emerge as a collective excitation of quantized lattice vibrations in a crystalline structure, akin to ripples on a pond's surface. These quasi-particles exhibit wave-like properties and play a crucial role in thermal conductivity, sound propagation, and other physical phenomena in solids. Their significance lies in understanding energy transport, acoustic properties, and the behavior of materials at microscopic scales.
