DESCRIPTION:Grand unified theories and many other quantum field theories p
 redict the existence of stable magnetic monopoles or other topological sol
 itons. They are usually studied at classical level\, and quantum correctio
 ns are only known in supersymmetric theories or at leading order in pertur
 bation theory in simple toy models. I show how masses and certain other pr
 operties of quantum solitons can be calculated fully non-perturbatively us
 ing lattice Monte Carlo simulations and present results for 't Hooft-Polya
 kov monopoles in SU(2) theory. I will also discuss possible uses of this t
 o understand confinement and other non-perturbative properties of gauge fi
 eld theories.\n
