Numerical simulation of non-central collisions of spherical magnets
Sean P. Bartz, Jacob Shaw
We present a computational model of non-central collisions of two spherical neodymium-iron-boron magnets, suggested as a demonstration of angular momentum conservation. Our program…
Laser-induced forces on atoms during ultrafast demagnetization
G. P. Zhang, Y. H. Bai
Laser-induced femtosecond demagnetization has attracted a broad attention as a possible candidate for information storage technology. However, whether or not lattice vibration dire…
Spin-phonon dispersion in magnetic materials
Mingqiang Gu, Y. H. Bai, G. P. Zhang +1
Microscopic coupling between the electron spin and the lattice vibration is responsible for an array of exotic properties from morphic effects in simple magnets to magnetodielectri…
First-principles insights into all-optical spin switching in the half-metallic Heusler ferrimagnet MnRuGa
G. P. Zhang, Y. H. Bai, M. S. Si +1
All-optical spin switching (AOS) represents a new frontier in magnetic storage technology -- spin manipulation without a magnetic field, -- but its underlying working principle is…
On Mixed Cages
Geoffrey Exoo
Mixed graphs have both directed and undirected edges. A mixed cage is a regular mixed graph of given girth with minimum possible order. In this paper mixed cages are studied. Upper…
Coefficient of restitution of a linear dashpot on a rigid surface
Sean P. Bartz
The linear dashpot model is applied to a single ball bouncing on a rigid surface. It is shown that when gravity is included the coefficient of restitution depends on impact velocit…
