Parity-Time Symmetry of Plasma Waves
Hong Qin
The susceptibility tensor of a homogeneous collisionless magnetized plasma possesses parity-time (PT) symmetry. For a stationary gyrotropic equilibrium, with the wave vector $\math…
Warm Topological Langmuir Cyclotron Wave
Virginia Billings, Hong Qin, Chuang Ren +1
Finite-temperature effects in magnetized electron plasmas create a new Weyl-point degeneracy between the warm Langmuir and right-circularly polarized waves. The associated topologi…
Algebraic discrete quantum harmonic oscillator with dynamic resolution scaling
Michael May, Hong Qin
We develop an algebraic formulation for the discrete quantum harmonic oscillator (DQHO) with a finite, equally-spaced energy spectrum and energy eigenfunctions defined on a discret…
Resonant instabilities mediated by drag and electrostatic interactions in laboratory and astrophysical dusty plasmas
Ben Y. Israeli, Amitava Bhattacharjee, Hong Qin
Dusty plasmas are known to support a diverse range of instabilities, including both generalizations of standard plasma instabilities and ones caused by effects specific to dusty sy…
Generalized Yee methods: Scalable symplectic finite element Maxwell solvers
Alexander S. Glasser, Hong Qin
Yee's finite-difference method preserves two crucial properties of Maxwell's equations -- locality and symplecticity -- and thereby enjoys two computational advantages: scalability…
Spin Hall effect of radiofrequency waves in magnetized plasmas
Yichen Fu, I. Y. Dodin, Hong Qin
In inhomogeneous media, electromagnetic-wave rays deviate from the trajectories predicted by the leading-order geometrical optics. This effect, called the spin Hall effect of light…
