Project title: The Calculation of Transition Pathways
Team members: Lilith, Mohmmad and Xikai
Background of the problem: Many problems in chemistry involve meta-stable states, where the system stays for certain period of time. An important problem is the transition mechanism from one meta-stable state to the other. The path of such transition is known as the minimum energy path, and the mathematical model is a differential equation with boundary conditions.
Mathematical methods: We use B-spline functions as basis functions, and solve the differential equations using a nonlinear least square algorithm.
Summary of results: We have implemented the algorithm in MATLAB, and studied a cluster of atoms modelled by the Lennard-Jones potential. Poster Presentation by the group
