Query: Competing Crystal Phases in the Lowest Landau Level   We show that the solid phase between the 1/5 and 2/9 fractional quantum Hall
states arises from an extremely delicate interplay between type-1 and type-2
composite fermion crystals, clearly demonstrating its nontrivial, strongly
correlated character. We also compute the phase diagram of various crystals
occurring over a wide range of filling factors, and demonstrate that the
elastic constants exhibit non-monotonic behavior as a function of the filling
factor, possibly leading to distinctive experimental signatures that can help
mark the phase boundaries separating different kinds of crystals.
