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
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
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.
Effect of Pt addition to AgAu bimetallic nanoclusters: A molecular dynamics study of AgAuPt ternary system
Abstract In this work addition of Pt atoms to Ag 0.5 Au 0.5 nanoclusters and formation of Ag 0.5− x Au 0.5− x Pt 2 x (with x  = 0.1, 0.17, 0.2, 0.25, 0.3, and 0.4) and total number of atoms equal to
Effect of pre-impact waves in an elastic rod on coefficient of restitution
Abstract The effect of pre-impact waves on the coefficient of restitution (COR) in longitudinal impact of a uniform elastic rod on a linear elastic or bilinear inelastic spring supported by a fix


Thermodynamics of Small Systems
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
Abstract: About a decade ago, biophysicists observed an approximately linear relationship between the combinatorial complexity of knotted DNA and the distance traveled in gel electrophoresis
