In this research project, processes of homogeneous and heterogeneous nucleation are investigated by computer simulations of an Ising lattice gas model. On the one hand, the analysis focuses on nucleation kinetics. On the other hand, system sizes with up to 10^12 Ising spins will be simulated which will break new ground. Systems of that size will enable the applicant to monitor homogeneous and heterogeneous nucleation at the same time in one single Ising lattice. This can be used to determine relative nucleation rates. The simulation and analysis algorithms of this project will be implemented on graphics processors (GPUs) which provide resources for a very efficient acceleration of scientific applications. The applicant already used GPUs successfully for accelerating computer simulations of the Ising model. In addition, it is planned to apply methods and concepts from statistical physics to problems arising in financial markets.
