Description
We critically discuss the algorithmic process of estimating spectral densities using the Hansen-Lupo-Tantalo method. A novel approach at finite volume is deployed to extract the spectrum of lattice gauge theories. As a case study, our discussion focuses on symplectic gauge theories with matter field consisting of a mixed fermion representation---fundamental and two-index antisymmetric one. We extensively discuss potential sources of systematic effects. The results obtained with the spectral densities are critically compared with conventional data analysis techniques, such as the generalised eigenvalue problem. Our algorithm and code can be applied to theories with other group and matter field content.
