Quantum Pseudospin Acoustics in Liquids

1979
The realization of Zavoiski’s ideas concerning acoustic EPR and NMR in fluids are discussed. A general relation between heat fluctuations and sound perturbations is found. Formulas for dipole-dipole and hyperfine AEPR and ANMR are derived. Experimental results for sound modulation of proton spin echoes in aqueous solutions of CuSO4·5H2O are presented.

Acoustic Analogies for Quantum Mechanics

2004
In Chap. 2, we considered the analogy between the propagation of electromagnetic waves and quantum waves, based on the formal similarity between the Helmholtz and the Schrodinger equation. However, a similar analogy holds for sound waves. This is to be expected since sound waves are not so different from electromagnetic waves.

Realization of chiral two-mode Lipkin–Meshkov–Glick models via acoustics

Reports on progress in physics. Physical Society
The chirality-controlled two-mode Lipkin–Meshkov–Glick (LMG) models are mimicked in a potential hybrid quantum system, involving two ensembles of solid-state spins coupled to a pair of interconnected surface-acoustic-wave cavities. With the assistance of

Quantum anomaly in acoustic parametric interaction

Journal of Physics C: Solid State Physics, 1974
A 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 Letters
An 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).
