Deep inelastic collision of two-dimensional anisotropic dipolar condensate solitons
(2022-03-01)
The possibility of generating stable anisotropic solitons in dipolar Bose–Einstein condensates (BECs) leads to a different scenario not possible in a nondipolar BEC with contact interaction. We study the statics and dynamics ...
Particle dynamics description of ‘‘BGK collisions’’ as a Poisson process
(American Geophysical Union, 2009-07-02)
The Gordeyev integral for plasma particles colliding with neutrals is obtained using a particle dynamics formalism in which the collisions are modeled as a discrete Poisson process. The result leads to an electron density ...
Theoretical study of collision dynamics of fullerenes on graphenylene and porous graphene membranes
(2020-11-01)
A comparative study regarding the behavior of graphene, porous graphene and graphenylene monolayers under high energy impact is reported. Our results were obtained using a computational model constructed to perform ...
The bouncing threshold in silica nanograin collisions
(Royal Society of Chemistry, 2017-05)
Using molecular dynamics simulations, we study collisions between amorphous silica nanoparticles. Our silica model contains uncontaminated surfaces, that is, the effect of surface hydroxylation or of adsorbed water layers ...
Nonlinear ball and beam control system identification
(2014)
The Ball and Beam system is a common didactical experiment in control laboratories that can be used to illustrate many different closed-loop control techniques. The plant itself is subjected to many nonlinear effects, which ...
Theory of ionization processes in positron-atom collisions
(Elsevier Science, 2006-12)
We review past and present theoretical developments in the description of ionization processes in positron-atom collisions. Starting from an analysis that incorporates all the interactions in the final state on an equal ...
Experimental observation of the collision of three vortex rings
(IOP Publisihing, 2015)
We investigate for the first time the motion, interaction and simultaneous
collision between three initially stable vortex rings arranged symmetrically,
making an angle of 120 degrees between their straight path lines. ...
