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…
