Abstract:
The heights of energy barriers separating two (macro-)states are useful for
estimating transition frequencies. In non-degenerate landscapes the
decomposition of a landscape into basins surrounding local minima connected
by saddle points is straightforward and yields a useful definition of
macro-states. In this work we develop a rigorous concept of barrier trees
for degenerate landscapes. We present a program that efficiently computes
such barrier trees, and apply it to two well known examples of landscapes.
