Magnetic reconnection as a driver for a sub-ion scale cascade in plasma turbulence
L. Franci, S. S. Cerri, F. Califano +6
A new path for the generation of a sub-ion scale cascade in collisionless plasma turbulence, triggered by magnetic reconnection, is uncovered by means of high-resolution two-dimens…
Low energy Langmuir cavitons: asymptotic limit of weak turbulence
P. Henri, F. Califano, C. Briand +1
Langmuir turbulence is an archetype of wave turbulence in plasma physics. By means of 1D-1V Vlasov-Poisson simulations, we show that coherent structures, called Langmuir cavitons,…
On the transition between the Weibel and the whistler instabilities
L. Palodhi, F. Califano, F. Pegoraro
The transition between non resonant (Weibel-type) and resonant (whistler) instabilities is investigated numerically in plasma configurations with an ambient magnetic field of incre…
Pressure tensor in the presence of velocity shear: stationary solutions and self-consistent equilibria
S. S. Cerri, F. Pegoraro, F. Califano +2
Observations and numerical simulations of laboratory and space plasmas in almost collisionless regimes reveal anisotropic and non-gyrotropic particle distribution functions. We inv…
Pressure anisotropy generation in a magnetized plasma configuration with a shear flow velocity
S. De Camillis, S. S. Cerri, F. Califano +1
The nonlinear evolution of the Kelvin Helmholtz instability in a magnetized plasma with a perpendicular flow close to, or in, the supermagnetosonic regime can produce a significant…
Undamped electrostatic plasma waves
F. Valentini, D. Perrone, F. Califano +4
Electrostatic waves in a collision-free unmagnetized plasma of electrons with fixed ions are investigated for electron equilibrium velocity distribution functions that deviate slig…
