When Quantum Fluctuations Meet Structural Instabilities: The Isotope- and Pressure-Induced Phase Transition in the Quantum Paraelectric NaOH
Sofiane Schaack, Etienne Mangaud, Erika Fallacara +3
Anhydrous sodium hydroxide, a common and structurally simple compound, shows spectacular isotope effects: NaOD undergoes a first-order transition, which is absent in NaOH. By combi…

Quantum driven proton diffusion in brucite-like minerals under high pressure
Sofiane Schaack, Philippe Depondt, Simon Huppert +1
We investigate the elementary steps at the microscopic level for proton diffusion in brucite under high pressure, which results from a complex interplay between two processes: the…
