The ab initio molecular dynamics
WebUsing the frameworks of density functional theory, we found a new class of three-dimensional (3D) topological insulators (TIs) in Pb2BiBrO6 and Pb2SeTeO6 double perovskites. Our ab initio theoretical calculations show that Pb2BiBrO6 and Pb2SeTeO6 are Z2 nontrivial, and their bandgaps are 0.390 eV and 0.181 eV, respectively. The topology … WebNon-adiabatic molecular dynamics (NAMD) is the method of choice to model these processes. We review new developments in quantum–classical dynamics, analytical …

WebMay 10, 2024 · Theoretical prediction on the elastic properties of superionic material is challenging due to the fast diffusion of cation/anion in the lattice. Here, we investigated the elastic properties of ${\\mathrm{Li}}_{2}\\mathrm{O}$ at elevated temperature and pressure using ab initio molecular dynamics (AIMD). We observed the superionic transition above … Web1 day ago · In this paper, we study the effect of different cationic functional groups (FGs) on the water and hydroxide ion diffusion mechanisms in nanoconfined AEM models, by comparing the effect of trimethyl alkyl ammonium (TMA) and imidazolium (IMI) FGs using fully atomistic ab initio molecular dynamics simulations.. The IMI FG was found to be a …
WebEmploying ab initio molecular dynamics simulations, a concerted mechanism with a barrier of 0.33 eV was suggested for cubic LLZO [10]. Further, from ab-initio molecular dynamics simulations, metadynamics and nudged elastic band calculations, two different mechanisms were identified: in the tetragonal phase, a synchro- WebAb initio molecular dynamics is an irreplaceable technique for the realistic simulation of complex molecular systems and processes from first principles.
