• Recent studies suggest the strong correlation between instantons and monopoles in the abelian gauge. We study instantons and monopoles in the SU(2) lattice gauge theory in the maximally abelian (MA) gauge. Using the 16^3×4 lattice, we find monopole dominance for instantons in the confinement phase at zero and finite temperatures. A linear-type correlation is found between the total monopole-loop length and the integral of the absolute value of the topological density (the total number of instantons and anti-instantons) in the MA gauge. We conjecture that instantons enhance the monopole-loop length and promote monopole condensation.
