Quantum anomaly in acoustic parametric interaction
Journal of Physics C: Solid State Physics, 1974A quantum theory of acoustic parametric interaction in piezoelectric semiconductors is developed. The rate of acoustic sum frequency generation is expressed in terms of the nonlinear conductivity coefficient gamma , which is obtained for arbitrarily degenerate electron statistics by solving the equation of motion for the one-electron density operator ...

Quantum weak measurement enhanced distributed acoustic sensing
Optics LettersAn enhanced distributed acoustic sensing (DAS) is proposed based on an extended Mach–Zehnder interferometer utilizing quantum weak measurement. The acoustic signals are encoded as the relative phase of the polarized light in several channels by fibers between optical fiber Bragg gratings (FBGs).
