Neoclassical equilibria as starting point for global gyrokinetic microturbulence simulations

Jonathan Graves, Laurent Villard, Stephan Brunner, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Thibaut Vernay

The implementation of linearized operators describing inter- and like-species collisions in the global gyrokinetic particle-in-cell code ORB5 [ S. Jolliet, Comput. Phys. Commun. 177, 409 (2007) ] is presented. A neoclassical axisymmetric equilibrium with s ...

Collision avoidance with obstacles in flocking for multi agent systems

Mehran Khaghani

Multi agent system is a system consist of multiple interacting agents. These systems tend to select the best solution for their problems. They can be used in different tasks which are hard for an individual or even a complex system to do. One of the most c ...

Anisotropic propagation and confinement of high frequency phonons in nanocomposites

Akihiro Sato

We show that self-ordered anodic aluminum oxide containing hexagonal arrays of cylindrical nanopores with submicron periodicity is a versatile model system for the exploration of rich phononic phenomena at gigahertz frequencies, which are intimately linked ...

Pseudosurface acoustic waves in hypersonic surface phononic crystals

We present a theoretical framework allowing to properly address the nature of surfacelike eigenmodes in a hypersonic surface phononic crystal, a composite structure made of periodic metal stripes of nanometer size and periodicity of 1 mu m, deposited over ...

Effect of capillary pressure and surface tension on the deformation of elastic surfaces by sessile liquid microdrops: An experimental investigation

Ramon Pericet Camara

Sessile liquid drops are predicted to deform an elastic surface onto which they are placed because of the combined action of the liquid surface tension at the periphery of the drop and the capillary pressure inside the drop. Here, we show for the first tim ...

A study of beam-beam effects in hadron colliders with a large number of bunches

Tatiana Pieloni

A particle beam is a collection of a large number of charges and represents an electromagnetic potential for other charges, therefore exerting forces on itself (space charge) and other beams (Beam-Beam Interactions, BBIs). The control of the BBIs in partic ...

Global gyrokinetic simulations of rho* and nu* scalings of turbulent transport

Laurent Villard, Trach-Minh Tran, Sébastien Jolliet, Ben McMillan

Turbulent transport dynamics and level are investigated with the 5D gyrokinetic global code GYSELA, modelling the Ion Temperature Gradient instability with adiabatic electrons. The heat transport exhibits large scale events, propagating radially in both di ...

Electronic excitations induced by the impact of coinage metal ions and clusters on a rare gas matrix: neutralization and luminescence

Wolfgang Harbich, Christoph Sieber

Low energy collisions of atomic ions and cluster ions with rare gas covered metal substrates can lead to strong light emission which is element and size specific. Instead of a direct energy transfer into the electronic system of the cluster the observed em ...

Collision-induced luminescence from the impact of ions and cluster ions on solid rare gases

Wolfgang Harbich, Christoph Sieber

Light emission during the collision of ions and cluster ions on a metal surface covered by rare gas matrices of variable thickness is reported. The light intensity as a function of distance from the metal surface follows the classical image dipole theory. ...

Velocity Scheduling Controller for a Nonholonomic Mobile Robot

Dominique Bonvin, Philippe Müllhaupt, Davide Buccieri

An improvement over classical dynamic feedback linearization for the control of a nonholonomic mobile robot is proposed. The use of a state extension of higher dimension than in the case of dynamic feedback linearization helps reject constant disturbances ...
