Three-dimensional deformations in single-layer antimonene and interaction with a Au(111) surface from first principles
José de Jesús Villalobos Castro, Thomas Pierron, Stephane Pons +3
Using density functional theory, we investigate the electronic structure of the alpha phase of an antimony monolayer in its isolated form and in contact to the (111) surface of gol…
Slip-dominated structural transitions
Kanka Ghosh, Oguz Umut Salman, Sylvain Queyreau +1
We use molecular dynamics to show that plastic slip is a crucial component of the transformation mechanism of a square-to-triangular structural transition. The latter is a stylized…
Phonon hydrodynamic regimes in sapphire
Takuya Kawabata, Kosuke Shimura, Yuto Ishii +7
When an ideal insulator is cooled, four regimes of thermal conductivity are expected to emerge one after another. Two of these, the Ziman and the Poiseuille, are hydrodynamic regim…
Rb2Ti2O5 : a layered ionic conductor at the sub-micrometer scale
Valerio Digiorgio, Karen Sobnath, Maria Luisa Della Rocca +4
Over the past few years, ionic conductors have gained a lot of attention given the possibility to implement them in various applications such as supercapacitors, batteries or fuel…
Near-critical dark opalescence in out-of-equilibrium SF
Valentina Martelli, Amaury Anquetil, Lin Al Atik +4
The first-order phase transition between the liquid and gaseous phases ends at a critical point. Critical opalescence occurs at this singularity. Discovered in 1822, it is known to…
High-field immiscibility of electrons belonging to adjacent twinned bismuth crystals
Yuhao Ye, Akiyoshi Yamada, Yuto Kinoshita +16
Bulk bismuth has a complex Landau spectrum. The small effective masses and the large g-factors are anisotropic. The chemical potential drifts at high magnetic fields. Moreover, twi…
