Query: Possible composite-fermion liquid as a crossover from Wigner crystal to
  bubble phase in higher Landau level   The ground state cohesive energies per electron of the composite fermion (CF)
Fermi sea, the Laughlin state and the charge density wave (CDW) at higher
Landau levels (LLs) are computed. It is shown that whereas for $n\geq 2$ LL,
the CDW state is generally more energetically preferable than those of the CF
liquid and the Laughlin liquid, the $\nu =4+1/6$ CF liquid state unexpectedly
has lower ground state energy than that of the CDW state. We suggest this CF
liquid between the Wigner crystal and the bubble phase may lead to the
crossover from the normal integer quantum Hall liquid to the novel re-entrant
integer quantum Hall state observed in the recent magneto-transport
experiments.
