[0005] Mechanism of superconductivity: electron pairing and "pair tuning" in superconducting materials
[0006] Professor Huang Kun's "Solid State Physics" introduced the "optical" wave in the crystal; the "optical" wave is a wave pattern of phonons vibrating in the crystal lattice at the wave number q→0 limit. "Solid State Physics" combined the simplified model of "one-dimensional double ion chain" for a specific description, and its frequency
[0007] ω→(2β(M+m) / Mm) 1 / 2 (1)
[0008] and the amplitude is:
[0009] B / A=-m / M (2)
[0010] Among them, A and B are the amplitudes of each ion in the chains of two ions alternately arranged in one dimension in the double-ion crystal respectively, and M and m are the masses of the two ions respectively (see page 108 of "Solid State Physics", written by Huang Kun , People's Education Press, unified ISBN 13012.0220, published in June 1966, first printed in January 1979).
[0011] The reason why it is called "optical" wave is bec...
