Data from: "From short-time diffusive to long-time ballistic dynamics: the unusual center-of-mass motion of quantum bright solitons" Open Access

Brownian motion is ballistic on short time scales and diffusive on long time scales. Our theoretical investigations indicate that one can observe the exact opposite - an anomalous diffusion process where initially diffusive motion becomes ballistic on longer time scales - in an ultracold atom system with a size comparable to macromolecules. This system is the center-of-mass motion of a quantum matter-wave bright soliton for which the dominant source of decoherence are three-particle losses. Our simulations show that such unusual center-of-mass dynamics should be observable on experimentally accessible time scales. For more information, please see the article in question, or refer to the README.txt file
