Diffusing up the hill: Dynamics and equipartition in highly unstable systems

M Šiler, L Ornigotti, O Brzobohatý, P Jákl, A Ryabov… - Physical review …, 2018 - APS
Stochastic motion of particles in a highly unstable potential generates a number of diverging
trajectories leading to undefined statistical moments of the particle position. This makes …
