摘要：We compute low-lying eigenmodes of the gauge covariant Laplace operator on the lattice at nite temperature. For classical congurations we show how the lowest mode localizes the monopole constituents inside calorons and that it hops upon changing the boundary conditions. The latter effect we observe for thermalized backgrounds, too, analogously to what is known for fermion zero modes. We propose a new lter for equilibrium congurations which provides link variables as a truncated sum involving the Laplacian modes. This method not only reproduces classical structures, but also preserves the conning potential, even when only a few modes are used.
