Simulating rare events in systems without detailed balance
Abstract:
Processes that happen rapidly, yet infrequently, are very difficult to
simulate, because of the long waiting times between events. Although
various methods have been developed for simulating rare events, these
are
generally only applicable to equilibrium systems where detailed balance
is
satisfied. Motivated by the problem of a bistable genetic switch, we
have
developed a method for calculating rate constants and obtaining
transition
paths in equilibrium or non-equilibrium systems. This "Forward Flux
Sampling" method has been applied to the flipping of a genetic switch
and
the translocation of a polymer through a pore.
