It is demonstrated experimentally that the effective separation of bidispersed microspheres (dust particles) in the underdamped and strongly coupled regime is realized using a designed dusty plasma ratchet. Experimental findings reveal that these dust particles can undergo directional transport at v…

We develop theoretical models for microscale breakdown under extremely high electric field conditions, by incorporating physical mechanisms associated with extremely strong electric fields, such as field emission, electron runaway, ion impact ionization, and the dynamics of fast atoms, which allows …

We investigate static and dynamic behaviors of experimentally realized strongly coupled two-dimensional finite clusters in a complex (dusty) plasma. Clusters, ranging in size from N (number of grains) = 1 to 50 are obtained using a highly precise control arm assembly BECAA (bidirectional electrode c…

Laguerre-Gaussian (LG) laser beams have many interesting applications due to their unique field structure. However, the generation of intense LG beams remains challenging because of the limited damage threshold of intensity for optical elements used for the conversion from normal Gaussian beams to L…

We employ well-known concepts from statistical physics, quantum field theories, and general topology to study magnetic reconnection and topology change and their connection in incompressible flows in the context of an effective field theory without appealing to magnetic field lines. We consider the …

Landau-damped oscillations in collisionless plasmas, described by van Kampen and Case, are quasimodes, representing a continuous superposition of singular eigenfunctions, not true eigenmodes. Recent work by Ng et al. shows that even rare collisions replace these singular modes with discrete regular …

Recombination effects are shown to modify the charge-state distribution achieved in the acceleration of heavy ions during high-intensity laser-solid interactions. A recombination package has been developed for particle-in-cell codes, which includes dielectronic, radiative, and three-body recombinati…

Electrostatic discharges occur in numerous media on a range of length scales, from microscopic discharges inside electronic materials to kilometer-long channels in air during natural lightning events. To study the mechanisms and behavior of electrostatic discharges inside materials, we measured the …

A spherical-implosion platform diagnosed with the “beamlets” scattered-light detector provides high sensitivity to the impact of plasma screening on inverse bremsstrahlung absorption. Contrary to the more restrictive screening length suggested previously [D. Turnbull et al., Phys. Rev. Lett. 130, 14…

We investigate with particle-in-cell simulation the transport of fast electrons of MeV under a kT-level magnetic field produced by a circular coil target, where the fast electrons are generated by a picosecond laser pulse with typical intensity of 5×1019W/cm2 adopted in fast ignition. The fast elect…

Inertial confinement of fusion plasmas can be realized using the dynamic Z pinch, an electromagnetically driven cylindrical implosion system that is also used to generate intense x rays. However, the Z pinch is subject to magnetic Rayleigh-Taylor (MRT) instability, which must be suppressed for pract…

We compare model solutions of a forced Kadomtsev-Petviashvili (fKP) equation with experimental observations of dust acoustic precursor solitons excited by a supersonically moving charged cylindrical object in a dusty plasma medium. The fKP equation is derived from a three-fluid-Poisson model of the …
