In the narrow direction, the wavefunction shrinks to the Heisenberg-limited size of the ground-state cyclotron motion. Removing the saddle enables studying the evolution of a Landau gauge condensate in "flat land" under the sole influence of interactions. Surprisingly, we find that Landau gauge condensates are unstable towards crystallization into arrays of droplets. This instability of states in the lowest Landau level has its classical analogy in the Kelvin-Helmholtz instability of counterflowing liquids. We explore the crossover of this instability from the lowest Landau level to the Thomas-Fermi regime. I will discuss prospects to extend this work towards fractional quantum Hall states of bosons.
