Interacting particles crossing barriers: spatial statistics, choice of route taken and role of interactions
Gulzar Ahmad, Andrew J Archer, Sergey Savel'ev +1
We consider the statistics of pairs of particles moving in a potential energy landscape exhibiting a choice of different pathways from a local minimum start point to the global ene…

Nonequilibrium statistics of barrier crossings with competing pathways
Gulzar Ahmad, Sergey Saveliev, Steven P Fitzgerald +2
Many biological, chemical, and physical systems are underpinned by stochastic transitions between equilibrium states in a potential energy. Here, we consider such transitions in a…
