Symmetries, weak symmetries and related solutions of the Grad-Shafranov equation
Giampaolo Cicogna, Francesco Pegoraro, Francesco Ceccherini
We discuss a new family of solutions of the Grad--Shafranov (GS) equation that describe D-shaped toroidal plasma equilibria with sharp gradients at the plasma edge. These solutions…
Ion dynamics and coherent structure formation following laser pulse self-channeling
Andrea Macchi, Alessandra Bigongiari, Francesco Ceccherini +5
The propagation of a superintense laser pulse in an underdense, inhomogeneous plasma has been studied numerically by two-dimensional particle-in-cell simulations on a time scale ex…
Generation and Observation of Coherent, Long--Lived Structures in a Laser--Plasma Channel
T. V. Liseykina, F. Ceccherini, F. Cornolti +9
In recent experiments of laser pulse interaction at relativistic intensities with a low density plasma, the proton radiography technique showed evidence of long--lived field struct…
Electric field dynamics and ion acceleration in the self-channeling of a superintense laser pulse
A. Macchi, F. Ceccherini, F. Cornolti +2
The dynamics of electric field generation and radial acceleration of ions by a laser pulse of relativistic intensity propagating in an underdense plasma has been investigated using…
Applications of Symmetry Methods to the Theory of Plasma Physics
Giampaolo Cicogna, Francesco Ceccherini, Francesco Pegoraro
The theory of plasma physics offers a number of nontrivial examples of partial differential equations, which can be successfully treated with symmetry methods. We propose three dif…
Symmetry properties of some Euler-type equations in plasma physics
F. Ceccherini, G. Cicogna, F. Pegoraro
We consider a system of partial differential equations, of interest to plasma physics, and provide all its Lie point symmetries, with their respective invariant solutions. We also…
