Smeared spectral functions from lattice QCD: opportunities and challenges
Shoji Hashimoto
A broad class of physical observables can be expressed in terms of smeared spectral functions. Important examples include the hadronic vacuum polarization contribution to the muon…
Spectral reconstruction from Euclidean lattice correlators through singular value decomposition
Ryutaro Tsuji, Shoji Hashimoto
Reconstructing spectral densities from Euclidean lattice correlators requires an inverse Laplace transform, which is inherently ill-conditioned when applied to numerical data with…
