Molecular Dynamics simulations of Al-Ti metallic alloy melts using a transferable machine-learning potential
Yuna Kato, Jürgen Brillo, Dirk Holland-Moritz +4
We investigate the structural and dynamical properties of binary aluminum-titanium liquid metallic alloys, as a function of temperature and composition. We make use of MD-simulatio…
Spreading droplets of yield-stress fluids with and without gravity
Linnea Heitmeier, Olfa D'Angelo, Maziyar Jalaal +1
We investigate the effect of gravity on the spreading of droplets of yield stress fluids, by performing both microgravity experiments (in a drop tower) and experiments under terres…
Shear-Rate Dependent Surface Tension of Glass-Forming Fluids
Linnea Heitmeier, Thomas Voigtmann
We investigate the interface of a glass-forming fluid showing non-Newtonian rheology. By applying shear flow in the interface, we detect that the surface tension depends on the she…
Homogeneous Nucleation of Undercooled Al-Ni melts via a Machine-Learned Interaction Potential
Johannes Sandberg, Thomas Voigtmann, Emilie Devijver +1
Homogeneous nucleation processes are important for understanding solidification and the resulting microstructure of materials. Simulating this process requires accurately describin…
Feature Selection for High-Dimensional Neural Network Potentials with the Adaptive Group Lasso
Johannes Sandberg, Thomas Voigtmann, Emilie Devijver +1
Neural network potentials are a powerful tool for atomistic simulations, allowing to accurately reproduce \textit{ab initio} potential energy surfaces with computational performanc…
Long-Wavelength Anomalies in the Asymptotic Behavior of Mode-Coupling Theory
S. K. Schnyder, F. Höfling, T. Franosch +1
We discuss the dynamic behavior of a tagged particle close to a classical localization transition in the framework of the mode-coupling theory of the glass transition. Asymptotic r…
Localization phenomena in models of ion-conducting glass formers
Jürgen Horbach, Thomas Voigtmann, Felix Höfling +1
The mass transport in soft-sphere mixtures of small and big particles as well as in the disordered Lorentz gas (LG) model is studied using molecular dynamics (MD) computer simulati…
Tagged-particle dynamics in a hard-sphere system: mode-coupling theory analysis
Th. Voigtmann, A. M. Puertas, M. Fuchs
The predictions of the mode-coupling theory of the glass transition (MCT) for the tagged-particle density-correlation functions and the mean-squared displacement curves are compare…
