@article{Geles2011LinkSC, title={Link smearing considered as MCRG transformation}, author={F. Geles and Christian B. Lang}, journal={arXiv: High Energy Physics - Lattice}, year={2011} }

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…

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
