Physical Review Letters, 2017 We study the shock waves in relativistic chiral matter. We argue that the conventional Rankine-Hugoinot relations are modified due to the presence of chiral transport phenomena. We show that the entropy discontinuity in a weak shock wave is quadratic in the pressure discontinuity when the effect of chiral transport becomes sufficiently large.

Shock Waves in Disordered Media [PDF]
Physical Review Letters, 2012 We experimentally investigate the interplay between spatial shock waves and the degree of disorder during nonlinear optical propagation in a thermal defocusing medium. We characterize the way the shock point is affected by the amount of disorder and scales with wave amplitude.

Shock wave velocity and shock pressure for low density powders: A novel approach [PDF]
, 1994 A novel approach is presented to predict the shock wave velocity as well as the shock wave pressure in powder materials. It is shown that the influence of the specific volume behind the shock wave on shock wave velocity and shock pressure decreases with ...

Effect of Porosity on Dynamic Response of Additive Manufacturing Ti-6Al-4V Alloys
Micromachines, 2022 Additive manufacturing is a rapidly developing manufacturing technology of great potential for applications. One of the merits of AM is that the microstructure of manufactured materials can be actively controlled to meet engineering requirements. In this

Shock waves on complex networks [PDF]
Scientific Reports, 2014 Power grids, road maps, and river streams are examples of infrastructural networks which are highly vulnerable to external perturbations. An abrupt local change of load (voltage, traffic density, or water level) might propagate in a cascading way and affect a significant fraction of the network.

Shock Waves in Relativistic Anisotropic Hydrodynamics [PDF]
, 2021 Shock wave solutions in anisotropic relativistic hydrodynamics are considered. A new phenomenon of anisotropy-related angular deflection of the incident flow by the shock wave front is described. Patterns of velocity and momentum transformation by the shock wave front are described.

The microphysics of collisionless shock waves [PDF]
Reports on Progress in Physics, 2016 Collisionless shocks, that is shocks mediated by electromagnetic processes, are customary in space physics and in astrophysics. They are to be found in a great variety of objects and environments: magnetospheric and heliospheric shocks, supernova remnants, pulsar winds and their nebul , active galactic nuclei, gamma-ray bursts and clusters of galaxies

ARTEMIS Observations of Plasma Waves in Laminar and Perturbed Interplanetary Shocks [PDF]
, 2020 The 'Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun' (ARTEMIS) mission provides a unique opportunity to study the structure of interplanetary shocks and the associated generation of plasma waves with frequencies between ~50-8000 Hz due to its long duration electric and magnetic field burst waveform ...

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.

Turbulence transmission in parallel modified shocks using ray tracing [PDF]
Astron.Astrophys. 460 (2006) 23-28, 2006 We apply a semi-classical approach of handling waves as quasiparticle gas in a slowly varying flow -- analogous to ray tracing -- to calculate the Alfven wave transmission parameters, the resulting cross-helicity of the waves and the scattering-centre compression ratio, for cases where the shock thickness is large enough for the turbulent waves in the ...
