Invaded cluster algorithm for a tricritical point in a diluted Potts model
The invaded-cluster approach is extended to 2D Potts model with annealed vacancies using random cluster representation. Geometrical arguments are used to propose the algorithm which converges well to tricritical point in two dimensional p arameter space spanned by temperature and chemical potential for vacancies. The tricritical point is identified as a s imultaneous onset of the percolation of Fortuin Kasteleyn-cluster and of the percolation of disordered geometric cluste r. We present the results for the location of tricritical point and the concentration of vacancies for q= 1, 2, 3 in good agreement with the best known results.
