Diffusive scattering of electrons by electron holes around injection fronts

Chaotic scattering around black holes

It is shown that the scattering of a charged test particle by a system of four extreme Reissner-Nordtröm black holes is chaotic in some cases. The fractal structure of the scattering angle and time delay functions is another manifestation of the existence of a nonattracting chaotic set: fractal basin boundaries were previously known. 04.25.-g,04.40.Nr,04.70.Bw,95.10.Fh Typeset using REVTEX 1

Electron Injection by Dephasing Electrons with Laser Fields

The authors seek to review injection concepts for plasma based acceleration. It is shown that regardless of injection mechanism, resultant beams will be similar due to wave structure. Also, most schemes employ the same basic processes, namely the dephasing of electrons by laser elds, and can thus be analyzed with similar approaches.

ELECTRON III: Effective mass theorem, dynamics of electrons and holes

Band structure basically tells us the exact quantum mechanical description of the electrons, and in principle all properties of solids can be calculated from it. The quantum mechanical solution is nothing but the wave functions of the ‘allowed’ electronic eiganstates. So, an electron in an eiganstate will ideally extend throughout the sample. In another words, the electron is everywhere in spac...

Scattering by Black Holes

Black holes, objects so compact that not even light can escape their gravitational pull, are among the most intriguing concepts of modern science. As Kip Thorne wrote in 1974: “Of all the conceptions of the human mind from unicorns to gargoyles to the hydrogen bomb perhaps the most fantastic is the black hole: a hole in space with a definite edge over which anything can fall and nothing can esc...
