Remarkable new behaviors of sound, analogous to quantum physics, are emerging from the amplitude of acoustic waves, which under the conditions of symmetry breaking may acquire a geometric phase that leads to non-conventional topology19. Elastic waves in parallelly coupled one-dimensional (1D) waveguid...

This is a difficult one to answer with a 30-second soundbite. You can find a few “explanations” on the web which don’t really explain it, and others which appear to get the explanation wrong. The simplest approach to explaining it is to say that the physics of absorption and emission...
The first term on the right-hand side of Equation (1) represents diffraction, the second term signifies absorption with 𝛿δ as the diffusivity of sound and nonlinearity is given by the third term, where 𝛽=1+𝐵/2𝐴β=1+B/2A is the coefficient of nonlinearity and 𝐵/𝐴B/A ...
