Magneto-optical response of chromium trihalide monolayers: chemical trends
A. Molina-Sánchez, G. Catarina, D. Sangalli +1
Chromium trihalides (CrI, CrBr and CrCl) form a prominent family of isostructural insulating layered materials in which ferromagnetic order has been observed down to th…
Twisted bilayer graphene: low-energy physics, electronic and optical properties
G. Catarina, B. Amorim, Eduardo V. Castro +2
Van der Waals (vdW) heterostructures ---formed by stacking or growing two-dimensional (2D) crystals on top of each other--- have emerged as a new promising route to tailor and engi…
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…
