Investigating episodic mass loss in evolved massive stars IV. Comprehensive analysis of dusty red supergiants in NGC 6822, IC 10, and WLM
E. Christodoulou, S. de Wit, A. Z. Bonanos +6
Mass loss shapes the fate of massive stars; however, the physical mechanism causing it remains uncertain. We present a comprehensive analysis of seven red supergiants, for which we…
Enhanced THz third-harmonic generation in graphene via hot-carriers in a topological cavity
Spyros Doukas, Ioannis Katsantonis, Thomas Koschny +2
Graphene is a promising material for nonlinear THz applications owing to its high third-order susceptibility and tunable optical properties. Its strong nonlinear response, driven b…
Multiple truly topological unidirectional surface magnetoplasmons at terahertz frequencies
Shengquan Fan, Tianjing Guo, Binbin Zhou +7
Unidirectional propagation based on surface magnetoplasmons (SMPs) has recently been realized at the interface of magnetized semiconductors. However, usually SMPs lose their unidir…
Don't torque like that. Measuring compact object magnetic fields with analytic torque models
J. J. R. Stierhof, E. Sokolova-Lapa, K. Berger +10
Context. Changes of the rotational period observed in various magnetized accreting sources are generally attributed to the interaction between the in-falling plasma and the large-s…
Robust multimode interference and conversion in topological unidirectional surface magnetoplasmons
Chao Liu, Ziyang Zhao, Tianjing Guo +6
We have theoretically investigated surface magnetoplasmons (SMPs) in a yttrium-iron-garnet (YIG) sandwiched waveguide. The dispersion demonstated that this waveguide can support to…
