Using the method of breaking of circular symmetry and of subsequent symmetryrestoration via projection techiques, we present calculations for theground-state energies and excitation spectra of N-electron parabolic quantumdots in strong magnetic fields in the medium-size range 10 <= N <= 30. Thephysical picture suggested by our calculations is that of finite rotatingelectron molecules (REMs) comprising multiple rings, with the rings rotatingindependently of each other. An analytic expression for the energetics of suchnon-rigid multi-ring REMs is derived; it is applicable to arbitrary sizes giventhe corresponding equilibrium configuration of classical point charges. We showthat the rotating electron molecules have a non-rigid (non-classical)rotational inertia exhibiting simultaneous crystalline correlations andliquid-like (non-rigidity) characteristics. This mixed phase appears in highmagnetic fields and contrasts with the picture of a classical rigid Wignercrystal in the lowest Landau level.
