Abstract

Exact eigen modes with orbital angular momentum (OAM) in the complex media of unmagnetized homogeneous plasmas are studied. Three exact eigen modes with OAM are derived, i.e., photons, phonons, and plasmons. The OAM of different plasma components are closely related to the charge polarities. For photons, the OAM of electrons and ions are of the same magnitude but opposite direction, and the total OAM is carried by the field. For the phonons and plasmons, their OAM are carried by the electrons and ions. Lastly, the OAM modes in plasmas and their characteristics can be explored for potential applications in plasma physics and accelerator physics.

Development of a helicon-wave excited plasma facility with high magnetic field for plasma–wall interactions studies

Journal Article Zhang, Guilu ; Huang, Tianyuan ; Jin, Chenggang ; ... - Plasma Science and Technology

Here, the high magnetic field helicon experiment system is a helicon wave plasma (HWP) source device in a high axial magnetic field ( B₀ ) developed for plasma–wall interactions studies for fusion reactors. This HWP was realized at low pressure (5 × 10^–3 – 10 Pa) and a RF (radio frequency, 13.56 MHz) power (maximum power of 2 kW) using an internal right helical antenna (5 cm in diameter by 18 cm long) with a maximum B 0 of 6300 G. Ar HWP with electron density ~10¹⁸–10²⁰ m^–3 and electron temperature ~4–7 eV was produced at high B₀ of 5100more »« less

Simulations of relativistic quantum plasmas using real-time lattice scalar QED

Journal Article Shi, Yuan ; Xiao, Jianyuan ; Qin, Hong ; ... - Physical Review E

Real-time lattice quantum electrodynamics (QED) provides a unique tool for simulating plasmas in the strong-field regime, where collective plasma scales are not well separated from relativistic-quantum scales. As a toy model, we study scalar QED, which describes self-consistent interactions between charged bosons and electromagnetic fields. To solve this model on a computer, we first discretize the scalar-QED action on a lattice, in a way that respects geometric structures of exterior calculus and U(1)-gauge symmetry. The lattice scalar QED can then be solved, in the classical-statistics regime, by advancing an ensemble of statistically equivalent initial conditions in time, using classical fieldmore »« less

A 29Si, 1H, and 13C Solid-State NMR Study on the Surface Species of Various Depolymerized Organosiloxanes at Silica Surface

Journal Article Protsak, Iryna S. ; Morozov, Yevhenii M. ; Dong, Wen ; ... - Nanoscale Research Letters

Three poly(organosiloxanes) (hydromethyl-, dimethyl-, and epoxymethylsiloxane) of different chain lengths and pendant groups and their mixtures of dimethyl (DMC) or diethyl carbonates (DEC) were applied in the modification of fumed silica nanoparticles (FSNs). The resulting modified silicas were studied in depth using ²⁹Si, ¹H, and ¹³C solid-state NMR spectroscopy, elemental analysis, and nitrogen adsorption-desorption (BET) analysis. The obtained results reveal that the type of grafting, grafting density, and structure of the grafted species at the silica surface depend strongly on the length of organosiloxane polymer and on the nature of the “green” additive, DMC or DEC. The spectral changes observedmore »« less

A lattice Maxwell system with discrete space–time symmetry and local energy–momentum conservation

Journal Article Xiao, Jianyuan ; Qin, Hong ; Shi, Yuan ; ... - Physics Letters. A

A lattice Maxwell system is developed here with gauge-symmetry, symplectic structure and discrete space–time symmetry. Noether's theorem for Lie group symmetries is generalized to discrete group symmetries for the lattice Maxwell system. As a result, the lattice Maxwell system is shown to admit a discrete local energy–momentum conservation law corresponding to the discrete space–time symmetry. A lattice model that respects all local conservation laws and geometric structures is as good as and probably more preferable than standard models on continuous space–time. It can also be viewed as an effective algorithm for the governing differential equations on continuous space–time.

The two-dimensional kinetic ballooning theory for ion temperature gradient mode in tokamak

Journal Article Xie, T. ; Zhang, Y. Z. ; Mahajan, S. M. ; ... - Physics of Plasmas

The two-dimensional (2D) kinetic ballooning theory is developed for the ion temperature gradient mode in an up-down symmetric equilibrium (illustrated via concentric circular magnetic surfaces). The ballooning transform converts the basic 2D linear gyro-kinetic equation into two equations: (1) the lowest order equation (ballooning equation) is an integral equation essentially the same as that reported by Dong et al., [Phys. Fluids B 4, 1867 (1992)] but has an undetermined Floquet phase variable, (2) the higher order equation for the rapid phase envelope is an ordinary differential equation in the same form as the 2D ballooning theory in a fluid modelmore »« less
