Hybrid static potentials from Laplacian Eigenmodes
Roman Höllwieser, Francesco Knechtli, Tomasz Korzec +2
We present a method for computing hybrid static quark-antiquark potentials in lattice QCD based on Laplace trial states. They are formed by eigenvector components of the covariant…

Performance of two-level sampling for the glueball spectrum in pure gauge theory
Lorenzo Barca, Francesco Knechtli, Michael Peardon +2
The computation of the glueball spectrum is particularly challenging due to the rapid decay of the signal-to-noise ratio of the correlation functions. To address this issue, advanc…
