First Principles Excitons in Periodic Systems with Gaussian Density Fitting and Ewald Potential Functions
M. A. GarcÃa-Blázquez, J. J. Palacios
Excitons, namely neutral excitations in a system of electrons arising from the electron-hole interaction, are often essential to explain optical measurements in materials. They are…

Amorphization-induced topological and insulator-metal transitions in bidimensional BiSb alloys
A. J. UrÃa-Ãlvarez, J. J. Palacios
Bismuth has been shown to be topological in its different allotropes and compounds, with one of the most notable examples being the Bi-Sb alloy, the first 3D topological insulator…
