Dirac plasmon polaritons and magnetic modes in topological-insulator nanoparticles
Nikolaos Kyvelos, Vassilios Yannopapas, N. Asger Mortensen +1
We demonstrate the existence of previously unreported magnetic modes with record-high magnetic Purcell factors in topological-insulator nanospheres. Focusing on bismuth selenide (B…
Tunable exciton polaritons in band-gap engineered hexagonal boron nitride
Pedro Ninhos, Christos Tserkezis, N. Asger Mortensen +1
We show that hexagonal boron nitride (hBN), a two-dimensional insulator, when subjected to an external superlattice potential forms a new paradigm for electrostatically tunable exc…
Self-hybridisation between interband transitions and Mie modes in dielectric nanoparticles
Christos Tserkezis, P. Elli Stamatopoulou, Christian Wolff +1
We discuss the possibility of self-hybridisation in high-index dielectric nanoparticles, where Mie modes of electric or magnetic type can couple to the interband transitions of the…
