Cold kinetic theory is not cold fluid theory: A collective mode in self-gravitating spheres
Mikael Tacu
Cold collisionless matter is usually described by pressureless fluid equations; this fails in three-dimensional spherical geometry. For the cold spherical case, kinetic and fluid d…
Imaginary part of the conductivity using Kramers-Kronig relations
Jean-Christophe Pain, Mikael Tacu
In order to obtain the frequency-dependent photo-absorption in a plasma, both the real and imaginary parts of the AC conductivity are required. The real part can be deduced from th…
Why Cold BGK Modes Are So Cool: Dispersion Relations from Orbit-Constrained Distribution Functions
Mikael Tacu
We derive analytic dispersion relations for cold, orbitally constrained systems governed by the Vlasov equation. For magnetized plasmas, we obtain the first explicit relation for t…
Nonlinear adiabatic electron plasma waves. II. Applications
D. Bénisti, D. F. G. Minenna, M. Tacu +2
In this article, we use the general theory derived in the companion paper [M. Tacu and D. Bénisti, Phys. Plasmas (2021)] in order to address several long-standing issues regarding…
Convenient analytical formula for cluster mean diameter and diameter dispersion after nucleation burst
Mikael Tacu, Alexander Khrabry, Igor Kaganovich
We propose a new method of estimating the mean diameter and dispersion of clusters formed in a cooling gas, right after the nucleation stage. Using a moment model developed by Frie…
Witness emittance growth caused by driver density fluctuations in plasma wakefield accelerators
V. A. Minakov, M. Tacu, A. P. Sosedkin +1
We discovered a novel effect that can cause witness emittance growth in plasma wakefield accelerators. The effect appears in linear or moderately nonlinear plasma waves. The witnes…
