We measure the topological susceptibility by cooling with an over-improved action. In contrast with usual cooling, large instantons survive over-improved cooling {\em indefinitely}. By varying the parameter of the over-improved cooling action, we measure the instanton size distribution.

    hep-lat 2026-06 unverdicted novelty 6.0 of 10

    Lattice computation of Wilson-'t Hooft loops supplies numerical evidence for dyon condensation at theta=2pi in SU(2) Yang-Mills.

  2. Winding number on 3D lattice

    hep-lat 2024-12 conditional novelty 6.0 of 10

    A tree-level improved lattice formula combined with an over-improved gradient flow reproduces integer winding numbers for T^3 to SU(2) maps on coarse lattices.

  3. Lattice gradient flows (de-)stabilizing topological sectors

    hep-lat 2024-11 conditional novelty 5.0 of 10

    Iwasaki and DBW2 gradient flows keep the topological charge of SU(2) gauge configurations stable at long flow times, unlike Wilson and Symanzik flows; DBW2 quantizes the charge already near t=0.5.
