Abstract

Evidence of discrete acoustic Rayleigh wave turbulence (DARWT) is reported on the free surface of complex viscoelastic materials under monochromatic excitation. These surface elastic non-linear Rayleigh waves exhibit dispersionless dynamics governed by bulk shear rigidity at coexistence with dispersive capillary waves supported by surface tension. Using Laser Doppler Vibrometry (LDV), the discrete Kolmogorov-Zakharov (KZ) spectrum is measured, characterized by a power-law envelope in an inertial cascade of discrete harmonics. When shear rigidity dominates, KZ-spectrum characterized by an omega-5/2 acoustic fingerprint is observed as a conservative solid-like scaling, theoretically predicted from the exact three-wave dispersionless resonance. Conversely, when surface tension dominates over bulk stresses, dispersive CW behavior under the usual omega-17/6 liquid-like scaling is recovered. These findings support a unique theoretical framework for understanding conservative DARWT and advance the field of surface wave turbulence in viscoelastic media with markedly non-Newtonian rheology. Acoustic Rayleigh wave turbulence represents a conservative mechanism for dispersionless energy transport through weakly nonlinear wave interactions across scales, with relevance to various physics fields, from soft matter and biological systems up to geophysical flows.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-06-07:

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 0.25.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
