On the control of electron heating for optimal laser radiation pressure ion acceleration
H. -G. Jason Chou, Anna Grassi, Siegfried H. Glenzer +1
We study the onset of electron heating in intense laser-solid interactions and its impact on the spectral quality of radiation pressure accelerated ions in both hole boring and lig…
Radiation pressure acceleration of high-quality ion beams using ultrashort laser pulses
H. -G. Jason Chou, Anna Grassi, Siegfried H. Glenzer +1
The generation of compact, high-energy ion beams is one of the most promising applications of intense laser-matter interactions, but the control of the beam spectral quality remain…
Impact of the laser spatio-temporal shape on Breit-Wheeler pair production
A. Mercuri-Baron, M. Grech, F. Niel +4
The forthcoming generation of multi-petawatt lasers opens the way to abundant pair production by the nonlinear Breit-Wheeler process, i.e., the decay of a photon into an electron-p…
Efficient generation of turbulent collisionless shocks in laser-ablated counter-streaming plasmas
Anna Grassi, Frederico Fiuza
Laser-ablated high-energy-density (HED) plasmas offer a promising route to study astrophysically relevant processes underlying collisionless shock formation, magnetic field amplifi…
Radiation Pressure Driven Ion Weibel Instability and Collisionless Shocks
Anna Grassi, Mickael Grech, Francois Amiranoff +2
The Weibel instability from counterstreaming plasma flows is a basic process highly relevant for collisionless shock formation in astrophysics. In this Letter we investigate, via t…
SMILEI: a collaborative, open-source, multi-purpose particle-in-cell code for plasma simulation
J. Derouillat, A. Beck, F. Pérez +10
SMILEI is a collaborative, open-source, object-oriented (C++) particle-in-cell code. To benefit from the latest advances in high-performance computing (HPC), SMILEI is co-developed…
Electron Weibel Instability in Relativistic Counter-Streaming Plasmas with Flow-Aligned External Magnetic Fields
A. Grassi, M. Grech, F. Amiranoff +3
The Weibel instability driven by two symmetric counter-streaming relativistic electron plasmas, also referred to as current-filamentation instability, is studied in a constant and…
Vlasov simulation of laser-driven shock acceleration and ion turbulence
Anna Grassi, Luca Fedeli, Andrea Sgattoni +1
We present a Vlasov, i.e. a kinetic Eulerian simulation study of nonlinear collisionless ion-acoustic shocks and solitons excited by an intense laser interacting with an overdense…
