Topological features in the ferromagnetic Weyl semimetal CeAlSi: Role of domain walls
M. M. Piva, J. C. Souza, V. Brousseau-Couture +8
In the ferromagnetic (FM) Weyl semimetal CeAlSi both space-inversion and time-reversal symmetries are broken. Our quantum oscillation (QO) data indicate that the FM ordering modifi…
Tuning the nontrivial topological properties of the Weyl semimetal CeAlSi
M. M. Piva, J. C. Souza, V. Brousseau-Couture +6
In the ferromagnetic Weyl semimetal CeAlSi both space-inversion and time-reversal symmetries are broken. We use external pressure as an effective tuning parameter and relate three…
Fröhlich polaron effective mass and localization length in cubic materials: degenerate and anisotropic electronic bands
Bogdan Guster, Pedro Melo, Bradley A. A. Martin +7
Polarons, that is, charge carriers correlated with lattice deformations, are ubiquitous quasiparticles in semiconductors, and play an important role in electrical conductivity. To…
Electronic Response Quantities of Solids and Deep Learning
Kevin Ryczko, Olivier Malenfant-Thuot, Michel Côté +1
We introduce a deep neural network (DNN) framework called the \textbf{r}eal-space \textbf{a}tomic \textbf{d}ecomposition \textbf{net}work (\textsc{radnet}), which is capable of mak…
Temperature dependence of the topological phase transition of BiTeI from first principles
Véronique Brousseau-Couture, Gabriel Antonius, Michel Côté
A topological phase transition from a trivial insulator to a topological insulator requires the bulk band gap to vanish. In the case of noncentrosymmetric materials,…
Study of Silicon Photomultiplier Performance in External Electric Fields
X. L. Sun, T. Tolba, G. F. Cao +149
We report on the performance of silicon photomultiplier (SiPM) light sensors operating in electric field strength up to 30 kV/cm and at a temperature of 149K, relative to their per…
