A Deep Learning Approach to Describing the Plasma Sheath

Ethan Webb, Yuzhi Li, Christopher McDevitt

Despite their ubiquity, the rich physics present in a plasma sheath has inhibited the development of a generally applicable description of this critical region. The present study u…

Similarity for downscaled kinetic simulations of electrostatic plasmas: reconciling the large system size with small Debye length

Yanzeng Zhang, Haotian Mao, Yuzhi Li +1

A simple similarity has been proposed for kinetic (e.g., particle-in-cell) simulations of plasma transport that can effectively address the longstanding challenge of reconciling th…

Resolving the mystery of electron perpendicular temperature spike in the plasma sheath

Yanzeng Zhang, Yuzhi Li, Bhuvana Srinivasan +1

A large family of plasmas has collisional mean-free-path much longer than the non-neutral sheath width, which scales with the plasma Debye length. The plasmas, particularly the ele…

Bohm criterion of plasma sheaths away from asymptotic limit

Yuzhi Li, Bhuvana Srinivasan, Yanzeng Zhang +1

The plasma exit flow speed at the sheath entrance is constrained by the Bohm criterion. The so-called Bohm speed regulates the plasma particle and power exhaust fluxes to the wall,…

Topological-charge dependence of radiation torque for an acoustic-vortex spanner

Yuzhi Li, Gepu Guo, Juan Tu +5

Based on the analyses of the wave front and the wave vector of an acoustic-vortex (AV) spanner generated by a circular array of point source, the principle of object rotation is in…
