Blast wave
A blast wave is a region of compressed gas that expands supersonically outward from an explosion, led by a shock front across which pressure and temperature rise abruptly.
Granular chain solitons
Granular chain solitons are non-dispersive pulses traveling along chains of elastic grains like steel spheres, predicted by Vitalii Nesterenko, with a fixed width of about five grain diameters.
Shock wave
A shock wave is a thin front in a fluid or solid across which pressure, temperature, and density rise almost instantaneously when something moves faster than sound.
Sine-Gordon equation
The sine-Gordon equation is a nonlinear hyperbolic partial differential equation whose kink and antikink solutions behave as solitons, with applications in Josephson junctions and field theory.
Solitary waves in granular chains
Solitary waves in granular chains are localized pulses of compressive force along elastic particle arrays. They propagate without changing shape due to the nonlinear Hertz contact law.
Soliton
A soliton, or soliton wave, is a localized wave pulse that keeps its shape and emerges from collisions with other solitons unchanged, behaving like a particle.
Sonic switch
A sonic switch, also called an acoustic switch, is a device that uses one acoustic or mechanical signal to control whether another acoustic signal is transmitted through a material.
