Collisionless converging ion flows can sustain particle energization over an extended path, but the field channel responsible for the energy gain is not always identifiable. In laser-driven bladed microtube implosion, energetic carbon ions were previously observed alongside a self-generated gigagaus…

Interactions in a plasma between microparticles of two different diameters are investigated. In these experiments, the smaller microparticles form a layer above the larger microparticles in the plasma sheath, and three-dimensional trajectories are determined from videos. The authors deduce ion-wake forces and microparticle charges from the measured oscillation frequencies.

A single dust particle confined in an asymmetric ratchet potential is periodically driven by two oppositely directed laser beams, forming an underdamped dusty plasma rocking ratchet. We experimentally investigate the transport dynamics of the particle under varying driving amplitudes and frequencies…

The induced magnetic field in an applied field magnetoplasmadynamic discharge device is a key physical quantity for plasma transport and electromagnetic feedback in the plasma discharge process. To clarify its spatial evolution and the associated driving mechanisms under steady operating conditions,…

Speckles, or laser hot spots, are the intensity maxima of optically smoothed laser beams that seed instabilities, making a quantitative statistical description of speckles of interest. Earlier statistical theories estimated the number of speckles above an intensity level set for optically smoothed b…

Distortions in the electron distribution function driven by intense temperature gradients critically influence the heat transport and the generation and evolution of magnetic fields in plasmas under the condition of inertial confinement fusion. Describing such kinetic behaviors at large spatiotempor…

Laser-driven spherical implosion experiments create some of the most extreme states of matter accessible in the laboratory. However, experimental observables in implosion experiments are highly integrated, meaning that measurements cannot be straightforwardly inverted to characterize the thermodynam…

This work demonstrates the impact of ion-electron collisions on ion transport for strongly inhomogeneous plasmas in the nonlocal regime, where collisionality is insufficient to enforce local thermal equilibrium due to sharp gradients. Ion heat conduction and viscous stress in both unmagnetized and m…

We investigate magnetohydrodynamic (MHD) turbulence in plane shear flows with a streamwise background magnetic field in the super-Alfvénic regime, i.e., when the flow velocity is larger than the local Alfvén speed. In this regime, turbulence is energetically supplied by large-scale shear of the flow…

This paper proposes an optimal control strategy to cool an antiproton plasma in a time much shorter than that required by an adiabatic process. The authors examine the length and stability of the plasma, in addition to its duration. The work suggests that optimal control techniques may be useful for experiments with plasmas, in particular with antimatter plasmas, which need to be confined and cooled before significant losses and annihilation occur.
