The Frequency-Dependent Spin Contribution to the Magnetoelectric Tensor of CrO: A First-Principles Study
Torsten Geirsson, Davide Sangalli, Alberto García-Cristóbal +1
The magnetoelectric (ME) effect provides a promising pathway for controlling magnetic functionalities using electric fields. While first-principles methods for the static linear ME…
Coherent Ultrafast Excitonic Oscillations in Monolayer WS
Jorge Cervantes-Villanueva, Alberto García-Cristóbal, Davide Sangalli +1
Monolayer transition metal dichalcogenides are a suitable platform for studying excitonic coherence in the light-matter coupling regime. We present an ab initio time-dependent GW-B…
Magnons in chromium trihalides from \emph{ab initio} Bethe-Salpeter equation
Ali Esquembre-Kučukalić, Khoa B. Le, Alberto García-Cristóbal +3
Chromium trihalides (CrX, with ) are layered ferromagnetic materials with rich physics and possible applications. Their structure consists of magnetic Cr atoms…
Unveiling exciton formation: exploring the early stages in time, energy and momentum domain
Valentina Gosetti, Jorge Cervantes-Villanueva, Selene Mor +9
Resolving the early-stage dynamics of exciton formation following non-resonant photoexcitation in time, energy, and momentum is quite challenging due to their inherently fast times…
Physics of excitons in layered BiI. Effects of dimensionality and crystal anisotropy
Jorge Cervantes-Villanueva, Fulvio Paleari, Alberto García-Cristóbal +2
We carry out a detailed theoretical study of the electronic and optical properties of bulk and monolayer bismuth triiodide (BiI), a layered metal halide, using the ab initio…
Semiempirical pseudopotential approach for nitride-based nanostructures and {\it ab initio} based passivation of free surfaces
Alejandro Molina-Sánchez, Alberto García-Cristóbal, Gabriel Bester
We present a semiempirical pseudopotential method based on screened atomic pseudopotentials and derived from \textit{ab initio} calculations. This approach is motivated by the dema…
