  Recent works on electric bubbles (including the experimental demonstration of
electric skyrmions) constitute a breakthrough akin to the discovery of magnetic
skyrmions some 15 years ago. So far research has focused on obtaining and
visualizing these objects, which often appear to be immobile (pinned) in
experiments. Thus, critical aspects of magnetic skyrmions - e.g., their
quasiparticle nature, Brownian motion - remain unexplored (unproven) for
electric bubbles. Here we use predictive atomistic simulations to investigate
the basic dynamical properties of these objects in pinning-free model systems.
We show that it is possible to find regimes where the electric bubbles can
present long lifetimes ($\sim$ ns) despite being relatively small ($\varnothing
<$ 2 nm). Additionally, we find that they can display stochastic dynamics with
large and highly tunable diffusion constants. We thus establish the
quasiparticle nature of electric bubbles and put them forward for the physical
effects and applications (e.g., in token-based Probabilistic Computing)
considered for magnetic skyrmions.
