Density functional theory for a hard disc fluid on graphics cards — •Marlon Ebert — Johannes Gutenberg Universität Mainz

Investigating the rheological properties of two dimensional fluids near the freezing transition provides interesting challenges. In order to approach this problem we use density functional theory (DFT) to determine the static density correlations around one and two test particles. Since DFT calculations in more then one dimension are usually computationally expensive we resort to applying graphics cards as massively parallel computational devices, using the CUDA language. We discuss the signatures of the freezing transition in the static correlations and compare to simulation results. An extension of the static DFT method aimed at the correlation functions under shear will be discussed. From these the rheological properties of the fluid can be deduced.
