Wave-function shock waves

Physical Review A, 1992
When a Rydberg state is suddenly excited to an autoionizing Rydberg state by a short-pulse core-electron excitation, a shock wave is created in the Rydberg electron's wave function. This shock wave originates at small r, at the excited core, and propagates outward.

Interstellar Shock Waves

Science, 1991
An understanding of interstellar shock waves is crucial in determining the structure of the interstellar medium. By causing the gas to radiate, interstellar shocks provide astronomers with valuable diagnostics on both the physical conditions in the interstellar medium and the energy source that produced the shock.

Attosecond Shock Waves

Physical Review Letters, 2013
Shock-wave formation is a generic scenario of wave dynamics known in nonlinear acoustics, fluid dynamics, astrophysics, seismology, and detonation physics. Here, we show that, in nonlinear optics, remarkably short, attosecond shock transients can be generated through a strongly coupled spatial and temporal dynamics of ultrashort light pulses ...

DELTA SHOCK WAVES AS A LIMIT OF SHOCK WAVES

Journal of Hyperbolic Differential Equations, 2007
We discus the existence of delta shock waves obtained as a limit of two shock waves. For that purpose we perturb a prototype of weakly hyperbolic 2 × 2 system (sometimes called the "generalized pressureless gas dynamics model") by an additional term (called the "generalized vanishing pressure"). The obtained perturbed system is strictly hyperbolic and

Shock Wave Physics

American Journal of Kidney Diseases, 1991
Extracorporeal shock wave lithotripsy has significantly altered the management of symptomatic renal and ureteral calculi. Yet in an effort to limit the potentially harmful effects of shock waves, while still maintaining or maximizing stone fragmentation, one must understand basic shock wave physics. This report presents a brief overview of the physical

Stability of shock waves

Soviet Physics Uspekhi, 1989
The progress already made in studies of the stability of shock waves and some tasks for the future are reviewed. The following aspects of the problem are discussed: 1) stability of shock waves as hydrodynamic discontinuities irrespective of the events which occur in the relaxation zone of a wave (this aspect includes also the problem of stability of a ...

Explosive-Induced Shock Waves. Part II. Oblique Shock Waves

Journal of Applied Physics, 1958
The explosive production of oblique shock waves in solids is analyzed in the approximation that third and higher order terms in the shock strength can be neglected, and a procedure is developed for calculating the attenuation of the shocks. Application is made to the problem of determining the equation of state of the burned explosives gas.
