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…
Exciton-polaritons of a 2D semiconductor layer in a cylindrical microcavity
José Nuno S. Gomes, Carlos Trallero-Giner, Nuno M. R. Peres +1
We describe exciton-polariton modes formed by the interaction between excitons in a 2D layer of a transition metal dichalcogenide embedded in a cylindrical microcavity and the micr…
Fresnel polarisation of infra-red radiation by elemental bismuth
Bruno S. C. Alexandre, Luís C. Martins, Jaime E. Santos +2
We revisit the classical problem of electromagnetic wave refraction from a lossless dielectric to a lossy conductor, where both media are considered to be non-magnetic, linear, iso…
Excitons in Phosphorene: A Semi-Analytical Perturbative Approach
J. C. G. Henriques, N. M. R. Peres
In this paper we develop a semi-analytical perturbation-theory approach to the calculation of the energy levels (binding energies) and wave functions of excitons in phosphorene. Ou…
Berry Phase Estimation in Gate-Based Adiabatic Quantum Simulation
Bruno Murta, G. Catarina, J. Fernandez-Rossier
Gate-based quantum computers can in principle simulate the adiabatic dynamics of a large class of Hamiltonians. Here we consider the cyclic adiabatic evolution of a parameter in th…
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…
