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…
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…
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…
Energizing charged particles by an orbit instability in a slowly rotating magnetic field
E. Palmerduca, H. Qin, S. A. Cohen
The stability of charged particle motion in a uniform magnetic field with an added spatially uniform transverse rotating magnetic field (RMF) is studied analytically. It is found t…
Topological Langmuir-cyclotron wave
Hong Qin, Yichen Fu
A theoretical framework is developed to describe the Topological Langmuir-Cyclotron Wave (TLCW), a recently identified topological surface excitation in magnetized plasmas. As a to…
