We compare the energies of different electron solids, such as bubble crystals with triangular and square symmetry and stripe phases, to those of correlated quantum liquids in partially filled intermediate Landau levels. Multiple transitions between these phases when varying the filling of the top-most partially filled Landau level explain the observed reentrance of the integer quantum Hall effect. The phase transitions are identified as first-order. This leads to a variety of measurable phenomena such as the phase co-existence between a Wigner crystal and a two-electron bubble phase in a Landau-level filling-factor range 4.15≲ν≲4.26, which has recently been observed in transport measurements under micro-wave irradiation.
