Tomographic analysis of reflectometry data II: the phase derivative
F. Briolle, R. Lima, R. Vilela Mendes
A tomographic technique has been used in the past to decompose complex signals in its components. The technique is based on spectral decomposition and projection on the eigenvector…
One-to-one direct modeling of experiments and astrophysical scenarios: pushing the envelope on kinetic plasma simulations
R. A. Fonseca, S. F. Martins, L. O. Silva +3
There are many astrophysical and laboratory scenarios where kinetic effects play an important role. These range from astrophysical shocks and plasma shell collisions, to high inten…
Beam loading in the nonlinear regime of plasma-based acceleration
M. Tzoufras, W. Lu, F. S. Tsung +6
A theory that describes how to load negative charge into a nonlinear, three-dimensional plasma wakefield is presented. In this regime, a laser or an electron beam blows out the pla…
Expansion of nanoplasmas and laser-driven nuclear fusion in single exploding clusters
F. Peano, J. L. Martins, R. A. Fonseca +6
The expansion of laser-irradiated clusters or nanodroplets depends strongly on the amount of energy delivered to the electrons and can be controlled by using appropriately shaped l…
A tomographic analysis of reflectometry data I: Component factorization
Francoise Briolle, Ricardo Lima, Vladimir I. Man'ko +1
Many signals in Nature, technology and experiment have a multi-component structure. By spectral decomposition and projection on the eigenvectors of a family of unitary operators, a…
Prospects for all-optical ultrafast muon acceleration
F. Peano, J. Vieira, R. Mulas +3
A scheme for fast, compact, and controllable acceleration of heavy particles in vacuum has been recently proposed [F. Peano et al., New J. Phys. 10 033028 (2008)], wherein two coun…
