Estudo do modelo XY diluído na rede Kagomé utilizando simulação Monte Carlo

The present investigation assessed the influence of quenched non-magnetic impurities over XY model in Kagome lattice. This study was performed using the Monte Carlos method and finite size scale theory in order to estimate BKT transition points with accuracy. The phase transition diagram obtained exhibits a region of topological order and a disordered region separated by a BKT transition line. The initial slope of the temperature with dilution outperformed value found for the square lattice.
