Hello guys! I just just wondering a general thing about calculations done in the field theory and those made in the lattice. In the field theory we have some results that in principle should match with the lattice ones in the thermodynamic limit. However, when we tried to solve the same problem in the lattice, calculations provide a different answer. Maths are checked to be correct Is there any case when this can happen? That some model can be studied using the field theory but when you go into the lattice, the model provides different answers¿ Thanks!
