Phonon–Photon–Spin Transduction: A First-Principles Pedagogical Derivation from Lattice Vibrations to Conditional Spin Response
This pedagogical technical note derives a connected model from a one-dimensional monoatomic lattice through acoustic phonons, strain, photoelastic refractive-index modulation, Stokes and anti-Stokes optical sidebands, and a conditional spin-population response. It explains why a realistic optical-to-spin step requires...
