I am happy to see that our latest paper was published this week in Physical Review Research. Because it combines new experimental results with theoretical simulations this is one of the longest papers I have worked on. We first show where a shaking with a lattice can lead to the growth of excitations in a condensate. Then we devellop the required theoretical description to show how this stabiliy diagram can be understood by considering modulational instabilities.
