Non-reciprocal magnons in a two dimensional crystal with off-plane magnetization
M. J. T. Costa, J. Fernández-Rossier, N. M. R. Peres +1
Non reciprocal spin waves have a chiral asymmetry so that their energy is different for two opposite wave vectors. They are found in atomically thin ferromagnetic overlayers with i…
Magneto-optical Kerr effect in spin split two-dimensional massive Dirac materials
G. Catarina, N. M. R. Peres, J. Fernández-Rossier
Two-dimensional (2D) massive Dirac electrons possess a finite Berry curvature, with Chern number , that entails both a quantized dc Hall response and a subgap full-quarter…
Excitonic magneto-optics in monolayer transition metal dichalcogenides: From nanoribbons to two-dimensional response
J. Have, N. M. R. Peres, T. G. Pedersen
The magneto-optical response of monolayer transition metal dichalcogenides (TMDs), including excitonic effects, is studied using a nanoribbon geometry. We compute the diagonal opti…
Optical orientation with linearly polarized light in transition metal dichalcogenides
G. Catarina, J. Have, J. Fernández-Rossier +1
We study the optical properties of semiconducting transition metal dichalcogenide monolayers under the influence of strong out-of-plane magnetic fields, using the effective massive…
Monolayer transition metal dichalcogenides in strong magnetic fields: Validating the Wannier model using a microscopic calculation
J. Have, G. Catarina, T. G. Pedersen +1
Using an equation of motion (EOM) approach, we calculate excitonic properties of monolayer transition metal dichalcogenides (TMDs) perturbed by an external magnetic field. We compa…
Impact of graphene on the polarizability of a neighbour nanoparticle: a dyadic Green's function study
Bruno Amorim, P. A. D. Gonçalves, M. I. Vasilevskiy +1
We discuss the renormalization of the polarizability of a nanoparticle in the presence of either (i) a continuous graphene sheet or (ii) a plasmonic graphene grating, taking into a…
