We investigate the emergence of self-hybridized thermal magnetoplasmons in doped graphene nanodisks at finite temperatures upon being subjected to an external magnetic field. Using a semianalytical approach, which fully describes eigenmodes and polarizability nanodisks, we show that hybridization originates from coupling transitions between thermally populated Landau levels localized magnetoplasmon resonances nanodisks. Owing their origin, these modes combine extraordinary magneto-optical response with strong field enhancement plasmons, making them ideal tool for achieving chiral light-matter interactions, additional advantage tunable through carrier concentration, field, temperature. As demonstration capabilities, supported by array enable perfect absorption emission.

We report the existence of previously unreported magnetic modes with record-high Purcell factors in topological-insulator nanospheres. Focusing on Bi$_{2}$Se$_{3}$, and based full electromagnetic Mie theory, we find arising from surface current conductive topological insulator due to delocalized states. These currents are induced by electrons topologically protected states within Dirac cone. Furthermore, demonstrate that plasmon polaritons resulting interaction between THz photons dramatically influence both electric transitions quantum emitters placed near Bi$_2$Se$_3$ nanospheres, providing significantly enhanced entering strong-coupling regime. findings indicate Bi$_{2}$Se$_{3}$ nanospheres exhibit a rich optical response, stemming bulk states, making them promising candidates for enhancing strong light--matter interactions fields nanophotonics technologies.

We demonstrate the existence of previously unreported magnetic modes with record-high Purcell factors (PFs) in topological-insulator nanospheres. Focusing on bismuth selenide (Bi2Se3), and based full electromagnetic Mie theory, we find arising from both displacement current loops bulk surface currents due to delocalized states, induced by electronic transitions between topologically protected states within Dirac cone discretized sphere finite size. Furthermore, discuss how plasmon polaritons, resulting interaction THz photons electrons, dramatically influence electric quantum emitters placed near Bi2Se3 nanospheres, significantly enhancing corresponding PFs. These findings position whose optical response is related a richness physical mechanisms, among most promising candidates for light–matter interactions nanophotonics technologies.
