First , I  was  obtained density of magnetization and  density of energy  curves of isotropic Heisenberg model on square lattice (2x2) using worm and dirloop_sse.
After I was obtained these curves with wolfram mathematica.
Curves for magnetization density(density of energy) obtained with mathematica and worm(sse)  is strongly differ  one from another.They must match.
I was attached the files of mathematica and Heis2x2.py.
