We numerically investigate the mechanism of super rebounds (rebounds in which the restitution coefficient is larger than unity) for head-on collisions between nanoclusters. It is confirmed that the temperature and the entropy of the nanocluters decrease after the super rebounds by our molecular dynamics simulations. It is also found that the initial metastable structure plays a key role for the emergence of the super rebounds. 
Jet-induced jammed states of granular jet impacts
The impacts of granular jets for both frictional and frictionless grains in two dimensions are numerically investigated. A dense flow with a dead zone emerges during the impact. From our
Turn on the super-elastic collision nature of coronal mass ejections through low approaching speed
TLDR
The study firmly advances the understanding of the super-elastic property of plasmoids, and does give new clues to deeply understand why and how the magnetic energy and/or thermal energy of the colliding plasmoid can be converted into kinetic energy in such an efficient way.
Molecular dynamics study of the surface scattering and capture of nanoparticles at high velocities
Abstract Classical molecular dynamics has been used to simulate the elastic scattering of single solid nano-particles from a flat rigid surface. The results show that with the inclusion of a weighted
Small nanoparticles, surface geometry and contact forces
TLDR
The results suggest that the nearly spherical nanoparticles are likely to enable some nonlinear dynamic phenomena, such as breathers and solitary waves observed in granular materials, both originating from the nonlinear contact force.

It is shown in this paper that the differential equations of macroscopic thermodynamics can be generalized in such a way that they apply as well to small (i.e., nonmacroscopic) systems. Conventional
