Non-equilibrium Roughness Evolution of Small Molecule Mixed Films Reflecting Equilibrium Phase Behavior

no code implementations8 Mar 2021 Alexander Hinderhofer, Jan Hagenlocher, Alexander Gerlach, Joachim Krug, Martin Oettel, Frank Schreiber

Understanding non-equilibrium phenomena, such as growth, and connecting them to equilibrium phase behavior is a major challenge, in particular for complex multicomponent materials.

Lattice gas study of thin film growth scenarios and transitions between them: Role of substrate

no code implementations5 Oct 2020 Eelco Empting, Miriam Klopotek, Alexander Hinderhofer, Frank Schreiber, Martin Oettel

Thin film growth is investigated in two types of lattice gas models where substrate and film particles are different, expressed by unequal interaction energy parameters.

Analytical classical density functionals from an equation learning network

1 code implementation28 Oct 2019 Shang-Chun Lin, Georg Martius, Martin Oettel

We explore the feasibility of using machine learning methods to obtain an analytic form of the classical free energy functional for two model fluids, hard rods and Lennard--Jones, in one dimension .

Phase diagrams and crystal-fluid surface tensions in additive and nonadditive two-dimensional hard disk mixtures

no code implementations9 May 2018 Shang-Chun Lin, Martin Oettel

Using density functionals from fundamental measure theory, phase diagrams and crystal-fluid surface tensions in additive and nonadditive (Asakura-Oosawa model) two-dimensional hard disk mixtures are determined for the whole range of size ratios $q$ between disks, assuming random disorder in the crystal phase.
