We discuss the challenges of extending convergence results of classical Krylov subspace methods to their block counterparts and propose a new approach to this analysis. Block KSMs such as block GMRES are generalizations of classical KSMs, and are meant to iteratively solve linear systems with multiple right-hand sides (a.k.a. a block right-hand side) all-at-once rather than individually....
An improvement to the widely used distillation technique is presented in the context of meson spectroscopy. Introducing meson profiles in distillation space and optimizing them for the different operators of interest significantly increases the overlap between the created states and the energy eigenstates at no considerable extra cost. These profiles give more versatility to the smearing...
