Our paper demonstrating both experimentally and theoretically the response of shaking a Bose-Einstein condensate was published today in Physical Review X. We indentified two regimes that depend upon frequency and modulation strength: One, forms repeatable wave patterns known as Faraday waves, and the second creates unexpected grains that may arise from shaking-induced quantum correlations.
