Riassunto
This thesis examines critical phenomena within statistical lattice systems, emphasizing the interplay of non-abelian local and global invariances in scalar field theories close to a critical phenomenon.
These studies include numerical simulations in two- and three-dimensional lattice systems, encompassing different gauge representations and lattice Hamiltonians.
We have used Monte Carlo simulations and Finite-Size Scaling theory to study the non-perturbative properties of the theories addressed.
