Large-scale simulations reveal defect-mediated stripe order loss in 2D systems, likely a Kosterlitz-Thouless phase transition. Results align with analytic scaling theory for phase diagrams.

Area of Science:

  • Condensed Matter Physics
  • Computational Physics
  • Statistical Mechanics

Background:

  • Two-dimensional systems like thin films and monolayers exhibit complex domain patterns.
  • Understanding phase transitions and elementary excitations in these systems is crucial for materials science.

Purpose of the Study:

  • To investigate the phase diagram and excitations of the 2D dipolar Ising model with long-range interactions.
  • To elucidate the mechanism of stripe order loss in large-scale systems.

Main Methods:

  • Large-scale computer simulations of systems up to 117,649 particles.
  • Combined fast multipole method and non-Metropolis Monte Carlo sampling for low-temperature, long-range interactions.
  • Analysis of heat capacity and observed excitations.

Main Results:

  • Evidence of twofold stripe order loss via a defect-mediated mechanism at high repulsive-to-attractive coupling ratios.
  • Simulations indicate a Kosterlitz-Thouless phase transition.
  • Results agree with analytic scaling theory, confirming the predicted phase diagram.

Conclusions:

  • The study confirms the Kosterlitz-Thouless nature of the phase transition in the simulated systems.
  • Analytic scaling theory accurately predicts the phase diagram, including defect-mediated and Ising-like disordering mechanisms.
  • The findings provide insights into pattern formation and phase transitions in various 2D physical systems.
