Dimensional crossover in the layeredxy-model

  • A. Schmidt
  • T. Schneider
Original Contributions


Using the Monte-Carlo technique we studied the isotropic layeredxy-model. We concentrate on the fall of the transition temperatureT c , the behavior of the specific heat and the vortex density with reduced thickness. Our approximate Ginzburg-Landau treatment suggests that the drop ofT c resulting from the dimensional crossover is a combination of fluctuation and boundary effects.

    Equation (7) forZ shows that the large positive eigenvalues ofP will be the most important values for the calculation. There-fore we can consider restricting ourselves to these important positive eigenvalues before making the Hubbard-Stratanovich transform. Thus we no longer need to shift the diagonal elements ofP Google Scholar
