Abstract:
A new quark-field smearing algorithm is defined which enables efficient calculations of a broad range
of hadron correlation functions. The technique applies a low-rank operator to define smooth fields that are
to be used in hadron creation operators. The resulting space of smooth fields is small enough that all
elements of the reduced quark propagator can be computed exactly at reasonable computational cost.
Correlations between arbitrary sources, including multihadron operators can be computed
a posteriori
without requiring new lattice Dirac operator inversions. The method is tested on realistic lattice sizes with
light dynamical quarks.
