Ultrastrong coupling of topologically protected edge and bulk magnetoplasmons without a dedicated cavity
F. Velli, P. Sai, M. Dub +6
In the ultrastrong light-matter coupling regime, the ability to confine the electric field to subwavelength scales and define an electromagnetic mode is essential. This task is typ…
Large magnetoreflectance and optical anisotropy due to flat bands in the frustrated kagome magnet HoAgGe
F. Schilberth, L. DeFreitas, K. Zhao +7
We report peculiar optical properties of the frustrated itinerant magnet HoAgGe, which exhibits multiple magnetically ordered states obeying the kagome spin-ice rule. The optical c…
Addressing Shape and Extent of Weyl cones in TaAs by Landau level spectroscopy
David Santos-Cottin, Jan Wyzula, Florian Le Mardelé +7
Tantalum arsenide, TaAs, is a prime example of a topological semimetal with two types of Weyl nodes, W1 and W2, whose bulk signatures have proven elusive. We apply Landau level spe…
Lorentz-boost-driven magneto-optics in a Dirac nodal-line semimetal
J. Wyzula, X. Lu, D. Santos-Cottin +13
Optical response of crystalline solids is to a large extent driven by excitations that promote electrons among individual bands. This allows one to apply optical and magneto-optica…
Optical conductivity signatures of open Dirac nodal lines
D. Santos-Cottin, M. Casula, L. de' Medici +7
We investigate the optical conductivity and far-infrared magneto-optical response of BaNiS, a simple square-lattice semimetal characterized by Dirac nodal lines that disperse e…
