Atomic insights into the quasi-elastic response in shock reloading of shocked metals
Results in Physics, 2021 The quasi-elastic response has drawn much attention as an interesting phenomenon in physics of shock wave. It has been revealed that heterogeneity features such as defects on the mesoscale play important roles in the quasi-elastic response of shocked ...

High-energy few-cycle pulses: post-compression techniques
Advances in Physics: X, 2021 Contemporary ultrafast science requires reliable sources of high-energy few-cycle light pulses. Currently two methods are capable of generating such pulses: post compression of short laser pulses and optical parametric chirped-pulse amplification (OPCPA).

Supernovae: An example of complexity in the physics of compressible fluids [PDF]
The European Physical Journal E, 2014 The supernovae are typical complex phenomena in fluid mechanics with very different time scales. We describe them in the light of catastrophe theory, assuming that successive equilibria between pressure and gravity present a saddle-node bifurcation. In the early stage we show that the loss of equilibrium may be described by a generic equation of the ...

Compressed modes for variational problems in mathematics and physics [PDF]
Proceedings of the National Academy of Sciences, 2013 Significance Intuition suggests that many interesting phenomena in physics, chemistry, and materials science are “short-sighted”—that is, perturbation in a small spatial region only affects its immediate surroundings. In mathematical terms, near-sightedness is described by functions of finite range.
