Gauge link smearing is widely used in lattice QCD computations. The idea is to remove the local (UV) fluctuations of the gauge field configurations while keeping the longer-range (IR) properties intact. Important applications are in the definitions of interpolating hadron operators as well as in updating the gauge field configurations with dynamical quarks in the so-called Hybrid Monte Carlo (HMC) algorithm. Here we study the effectiveness of various smearing methods and try to quantify these…

Analytic smearing of SU(3) link variables in lattice QCD
An analytic method of smearing link variables in lattice QCD is proposed and tested. The differentiability of the smearing scheme with respect to the link variables permits the use of modern Monte
Trivializing Maps, the Wilson Flow and the HMC Algorithm
In lattice gauge theory, there exist field transformations that map the theory to the trivial one, where the basic field variables are completely decoupled from one another. Such maps can be

Hadron spectroscopy with dynamical chirally improved fermions
We simulate two dynamical, mass-degenerate light quarks on ${16}^{3}\ifmmode\times\else\texttimes\fi{}32$ lattices with a spatial extent of 2.4 fm using the chirally improved Dirac operator. The
A New approach to Ginsparg-Wilson fermions
We expand the most general lattice Dirac operator D in a basis of simple operators. The Ginsparg-Wilson equation turns into a system of coupled quadratic equations for the expansion coefficients. Our
Flavor symmetry and the static potential with hypercubic blocking
The static potential measured on HYP smeared lattices agrees with the thin link potential at distances $r/ag~2$ and has greatly reduced statistical errors and will be used in forthcoming dynamical simulations of HYP staggered fermions.

Improved smoothing algorithms for lattice gauge theory
The relative smoothing rates of various gauge field smoothing algorithms are investigated on ${\cal O}(a^2)$-improved $\suthree$ Yang--Mills gauge field configurations. In particular, an ${\cal
