Model of pulsar pair cascades in non uniform electric fields: growth rate, density profile and screening time
Fábio Cruz, Thomas Grismayer, Simon Iteanu +2
Time-dependent cascades of electron-positron pairs are thought to be the main source of plasma in pulsar magnetospheres and a primary ingredient to explain the nature of pulsar rad…
Laser-Driven, Ion-Scale Magnetospheres in Laboratory Plasmas. I. Experimental Platform and First Results
D. B. Schaeffer, F. D. Cruz, R. S. Dorst +7
Magnetospheres are a ubiquitous feature of magnetized bodies embedded in a plasma flow. While large planetary magnetospheres have been studied for decades by spacecraft, ion-scale…
Laser-Driven, Ion-Scale Magnetospheres in Laboratory Plasmas. II. Particle-in-cell Simulations
Filipe D. Cruz, Derek B. Schaeffer, Fábio Cruz +1
Ion-scale magnetospheres have been observed around comets, weakly-magnetized asteroids, and localized regions on the Moon, and provide a unique environment to study kinetic-scale p…
Coherent emission from QED cascades in pulsar polar caps
Fábio Cruz, Thomas Grismayer, Alexander Y. Chen +2
Pulsar magnetospheres are thought to be filled with electron-positron plasma generated in pair cascades. The driving mechanism of these cascades is the emission of gamma-ray photon…
Kinetic instability in inductively oscillatory plasma equilibrium
Fábio Cruz, Thomas Grismayer, Luis O. Silva
A uniform in space, oscillatory in time plasma equilibrium sustained by a time-dependent current density is analytically and numerically studied resorting to particle-in-cell simul…
Kinetic model of large-amplitude oscillations in neutron star pair cascades
Fábio Cruz, Thomas Grismayer, Luis O. Silva
Electron-positron pair cascades developed in the extreme electromagnetic fields of neutron star polar caps are considered a key source of magnetospheric plasma in these objects. We…
