• The ground-state phase diagram of 2D electrons in a high Landau level (index N = 2) is studied by the density-matrix renormalization group method. Pair correlation functions are systematically calculated for various filling factors from nu = 1/8 to 1/2. It is shown that the ground-state phase diagram consists of three different charge density wave states called stripe phase, bubble phase, and Wigner crystal. The boundary between the stripe and the bubble phases is determined to be nu(s-b)c approximately 0.38, and that for the bubble phase and Wigner crystal is nu(b-W)c approximately 0.24. Each transition is of first order.
