Excitonic Magneto-Optical Kerr Effect in 2D Transition Metal Dichalcogenides Induced by Spin Proximity
J. C. G. Henriques, G. Catarina, A. T. Costa +2
In this paper we develop the excitonic theory of Kerr rotation angle in a two-dimensional (2D) transition metal dichalcogenide at zero magnetic field. The finite Kerr angle is indu…
Tuning the exchange bias on a single atom from 1 mT to 10 T
Kai Yang, William Paul, Fabian D. Natterer +8
Shrinking spintronic devices to the nanoscale ultimately requires localized control of individual atomic magnetic moments. At these length scales, the exchange interaction plays im…
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…
Engineering the eigenstates of coupled spin-1/2 atoms on a surface
Kai Yang, Yujeong Bae, William Paul +8
Quantum spin networks having engineered geometries and interactions are eagerly pursued for quantum simulation and access to emergent quantum phenomena such as spin liquids. Spin-1…
Scattering of graphene plasmons at abrupt interfaces: an analytic and numeric study
A. J. Chaves, B. Amorim, Yu. V. Bludov +2
We discuss the scattering of graphene surface plasmon-polaritons (SPPs) at an interface between two semi-infinite graphene sheets with different doping levels and/or different unde…
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…
