Propagation of acceleration waves in random media
… which models the time evolution of the wave amplitude: The analysis also reveals that there exists a critical amplitude that determines whether the wave amplitude decays, or blows-up rapidly to infinity. In the latter case, as the wave amplitude increases, the wavefront becomes thinner …

Tidal interactions between planets and stars
… the waves undergo instability and break above a critical amplitude. A model for the tidal dissipation that results from this process is presented, and its validity is verified by numerical integrations of the linear tidal response, in an extensive set of stellar models. The dissipation is …

Droplet Rebound and Atomization Characteristics of Vibrating Surfaces
… by keeping roughness constant and increasing the amplitude of the vibration to observe the critical amplitude at which atomization is initiated. The surface roughness is varied for the second set of experiments. The data is quantified using image processing of the high-speed videos to obtain the …

The mode-dependent dynamics of nonlinear nanomechanical resonators
… allows for closed-form scaling of the critical amplitude and dynamic range at arbitrary mode number and tension. We extend this approach to scale the relative influence of bending, tension, and nonlinearity with increasing mode number n, finding that bending and nonlinear influences …

Interfacial properties of fluid phases in two dimensions and of three-component surfactant systems
… complex fluids. The first problem concerns the critical behavior of the thickness of interface of simple fluids in two dimensions of space. We study this problem using both theory and computer simulations. In our theoretical study of this problem, the equilibrium interface is assumed, in accord …
