On the Locality and Scaling of Overlap Fermions at Coarse Lattice Spacings
Terrence Draper, Nilmani Mathur, Jianbo Zhang +7
The overlap fermion offers the considerable advantage of exact chiral symmetry on the lattice, but is numerically intensive. This can be made affordable while still providing large…
Charmonium Spectrum from Quenched QCD with Overlap Fermions
S. Tamhankar, A. Alexandru, Y. Chen +7
We present the first study of the charmonium spectrum using overlap fermions, on quenched configurations. Simulations are performed on lattices, with Wilson gauge…
The Negativity of the Overlap-Based Topological Charge Density Correlator in Pure-Glue QCD and the Non-Integrable Nature of its Contact Part
I. Horvath, A. Alexandru, J. B. Zhang +7
We calculate the lattice two-point function of topological charge density in pure-glue QCD using the discretization of the operator based on the overlap Dirac matrix. Utilizing dat…
Inherently Global Nature of Topological Charge Fluctuations in QCD
I. Horvath, A. Alexandru, J. B. Zhang +8
We have recently presented evidence that in configurations dominating the regularized pure-glue QCD path integral, the topological charge density constructed from overlap Dirac ope…
Charmonium Spectrum from Quenched QCD with Overlap Fermions
S. Tamhankar, A. Alexandru, Y. Chen +7
We present preliminary results using overlap fermions for the charmonium spectrum, in particular for hyperfine splitting. Simulations are performed on lattices, wi…
The Sequential Empirical Bayes Method: An Adaptive Constrained-Curve Fitting Algorithm for Lattice QCD
Ying Chen, Shao-Jing Dong, Terrence Draper +7
We introduce the ``Sequential Empirical Bayes Method'', an adaptive constrained-curve fitting procedure for extracting reliable priors. These are then used in standard augmented-$χ…
