Instability of Velocity-Verlet Integrator as Stochastic Process — •Lothar Brendel — Universität Duisburg-Essen

The Velocity-Verlet integrator is ubiquitous in simulations of classical many-body systems. Though being time symmetric, it is known to be stable ``only'' on exponentially long times. We model its loss of stability as a stochastic process and compare the resulting characteristics to actual simulations at the verge of stability.
