Plasma rotation driven by lasers with zero angular momentum
Camilla Willim, Thales Silva, LuÃs Oliveira Silva +1
We present a novel mechanism in which plasma electrons and ions optically acquire angular momentum during local pump depletion of an azimuthally polarized laser, despite the laser…

Phase-Space Shaping in Wakefield Accelerators due to Betatron Cooling
Pablo J. Bilbao, Thales Silva, Luis O. Silva
Plasma-based accelerators are beginning to employ relativistic beams with unprecedented charge and ultrashort durations. These dense driver beams can drive wakes even in high-densi…

The electron cyclotron maser instability in laser-ionized plasmas
Thales Silva, Pablo J. Bilbao, Luis O. Silva
We show that circularly polarized lasers create plasmas with long-lasting ring-shaped weakly relativistic momentum distributions which, in the presence of an ambient magnetic field…
