DOI: 10.1002/mma.10926

Abstract: We present and analyze a second‐order numerical scheme with variable time steps for a liquid thin film coarsening model, which is a Cahn–Hilliard‐type equation with a singular Leonard–Jones energy potential. The fully discrete scheme is… read more here.

DOI: 10.1021/acs.jctc.3c00126

Abstract: We compare several established approaches for propagating wave functions and calculating hopping probabilities within the fewest switches surface hopping (FSSH) algorithm for difficult cases with many electronic states and many trivial crossings. If only a… read more here.
