چکیده
Front propagation in partially ionized dense plasma is described by reaction{diiusion equations. We introduce the new method of Markoo automata for the stochastic simulation of reaction and diiusion in dense plasma which is capable to perform simulations fast and accurate. The method is applied to the investigation of ionization fronts of diierent shape. A comparison with analytic results for proole and velocity of plane fronts connrms the stochastic simulation data. Furthermore , we present data for an expanding ionization spot. Zusammenfassung Die Frontausbreitung in teilweise ionisiertem dichtem Plasma wird durch Reaktions{Diiusions{Gleichungen beschrieben. Wir f uhren eine neue Methode zur stochastischen Simulation der Reaktionen und der Diiusion in dichtem Plasma ein, die wir Markoo{Automaten nennen. Damit sind wir in der Lage, schnelle und sehr genaue Simulationen durchzuf uhren. Wir wenden die Methode auf die Untersuchung von Ionisationsfronten ver-schiedener Form an. Ein Vergleich mit analytischen Resul-taten f ur das Prool und die Geschwindigkeit von ebenen Fron-ten bestt atigt die Daten der stochastischen Simulation. Weiterhin prr asentieren wir Daten f ur einen expandierenden Ionisationsseck.

Tunneling-assisted impact ionization fronts in semiconductors
We discuss a type of ionization front in layered semiconductor structures. The propagation is due to the interplay of band-to-band tunneling and impact ionization. Our numerical simulations show that the front can be triggered when an extremely sharp voltage ramp (;10 kV/ns) is applied in reverse direction to a Si p – n – n structure that is connected in series with an external load. The trigge...

Finite element method (FEM) is one of the most famous methods which has many applications in varies studies such as the study of crack propagation in engineering structures. However, unless extremely fine meshes are employed, problem arises in accurately modelling the singular stress field in the singular element area around the crack tip. In the present study, the crack growth simulation has b...

One of the interesting Laser-Plasma phenomena, when the laser power is high and ultra intense, is the generation of large amplitude plasma waves (Wakefield) and electron acceleration. An intense electromagnetic laser pulse can create plasma oscillations through the action of the nonlinear pondermotive force. electrons trapped in the wake can be accelerated to high energies, more than 1 TW. Of t...
