Hydrogenated carbon structures as directional sub-GeV dark matter detectors
Tomás Arias, Antonino Bellinvia, Gianluca Cavoto +5
We propose hydrogenated carbon structures as targets with a remarkable sensitivity to dark matter-nucleon interactions, in the mass range between the 1 MeV and 100 MeV. The ejectio…
Elastic effects of vacancies in strontium titanate: Short- and long-range strain fields, elastic dipole tensors, and chemical strain
Daniel A. Freedman, D. Roundy, T. A. Arias
We present a study of the local strain effects associated with vacancy defects in strontium titanate and report the first calculations of elastic dipole tensors and chemical strain…
Ab initio mechanical response: internal friction and structure of divacancies in silicon
H. Ustunel, D. Roundy, T. A. Arias
This letter introduces ab initio study of the full activation-volume tensor of crystalline defects as a means to make contact with mechanical response experiments. We present a the…
Robust ab initio calculation of condensed matter: transparent convergence through semicardinal multiresolution analysis
I. P. Daykov, T. D. Engeness, T. A. Arias
We present the first wavelet-based all-electron density-functional calculations to include gradient corrections and the first in a solid. Direct comparison shows this approach to b…
