Inner core composition paradox revealed by sound velocities of Fe and Fe-Si alloy

Nature Communications, 2022
The origin of the observed low shear wave velocity in the solid inner core is unclear. Here, the authors report shear wave velocities of iron and iron-silicon alloy under Earth’s core conditions by shock compression and find that neither the effect of ...

Shockwaves in Supernovae: New Implications on the Diffuse Supernova Neutrino Background

, 2009
We investigate shock wave effects upon the diffuse supernova neutrino background using dynamic profiles taken from hydrodynamical simulations and calculating the neutrino evolution in three flavors with the S-matrix formalism. We show that the shock wave

Shock Waves in Nanomechanical Resonators [PDF]

Physical Review Letters, 2008
The dream of every surfer is an extremely steep wave propagating at the highest speed possible. The best waves for this are would be shock waves, but are very hard to surf. In the nanoscopic world the same is true: the surfers in this case are electrons riding through nanomechanical devices on acoustic waves.

Elastic-plastic coupled α→ω phase transformation of zirconium under shock loading: experiments and non-hydrostatic thermodynamic-based modeling

Journal of Materials Research and Technology
Modeling the martensitic transformation of solid materials under shock loading is still an unsolved problem. One of the key challenges is the effect of shear stress and elastoplastic coupling on the dynamic response.

Shock accelerated vortex ring [PDF]

, 2009
The interaction of a shock wave with a spherical density inhomogeneity leads to the development of a vortex ring through the impulsive deposition of baroclinic vorticity.

Thermodynamically consistent phase-field model for pressure-induced multiphase phase transformation of metals under intensive dynamic loading

Journal of Materials Research and Technology
Understanding the pressured-induced multiphase phase transformation (MPT) of metals at high strain rate is of great technical and scientific interest. Despite of several decades of studies, the pressured-induced MPT of metals at high strain rate is far ...

Interactions of energetic electrons with ULF waves triggered by interplanetary shock: Van Allen Probes observations in the magnetotail [PDF]

, 2014
We present in situ observations of a shock-induced substorm-like event on 13 April 2013 observed by the newly launched Van Allen twin probes. Substorm-like electron injections with energy of 30-500 keV were observed in the region from L∼5.2 to 5.5 ...
