3.

Perform the simulations for the 2D Ising lattice model using the code from example 4 at different temperatures in order to find Curie temperature. (Hint: It should be somewhere between T=2 and T=3) for two lattice sizes of your choice (do not go beyond N_x=16, it'll take too long). Which way does the T_c shift for smaller system? Explain.

4.

Perform the simulations for the 2D Ising lattice model with the periodic boundary conditions making the appropriate change in the code from example 4, at different temperatures in order to find Curie temperature. (Hint: It should be somewhere between T=2 and T=3) for two lattice sizes of your choice (do not go beyond N_x=16, it'll take too long). Compare the size effects to the previous problem. Explain the difference.
