Journal ArticleDOI
Volume dependence of the energy spectrum in massive quantum field theories. II. Scattering states
TL;DR: The low-lying energy values associated to energy eigenstates describing two stable particles enclosed in a (space-like) box of sizeL are shown to be expandable in an asymptotic power series of 1/L as mentioned in this paper.
Journal ArticleDOI
Two-particle states on a torus and their relation to the scattering matrix
TL;DR: In this paper, the energy spectrum of a system of two particles enclosed in a box with periodic boundary conditions is determined by the scattering phases at these energies, and exact exact formulae are derived which can be used to compute the energy levels given the scattering phase.
Journal ArticleDOI
Volume dependence of the energy spectrum in massive quantum field theories. I. Stable particle states
TL;DR: In this paper, a detailed proof of this basic relation is given for all orders of perturbation theory in arbitrary massive quantum field theories, which follows from an apparently universal asymptotic formula, which relates Δm to certain forward elastic scattering amplitudes.
Journal ArticleDOI
Properties and uses of the Wilson flow in lattice QCD
TL;DR: Theoretical and numerical studies of the Wilson flow in lattice QCD suggest that the gauge field obtained at flow time t > 0 is a smooth renormalized field as discussed by the authors.
Journal ArticleDOI
Perturbative analysis of the gradient flow in non-abelian gauge theories
Martin Lüscher,Peter Weisz +1 more
TL;DR: The gradient flow in non-abelian gauge theories is defined by a local diffusion equation that evolves the gauge field as a function of the flow time in a gauge-covariant manner as mentioned in this paper.
