Classical Limits of Scalar and Tensor Gauge Operators Based on the Overlap Dirac Matrix
Andrei Alexandru, Ivan Horvath, Keh-Fei Liu
It was recently proposed by the second author to consider lattice formulations of QCD in which complete actions, including the gauge part, are built explicitly from a given Dirac o…

New results using the canonical approach to finite density QCD
Anyi Li, Andrei Alexandru, Keh-Fei Liu
We present some new results regarding simulations of finite density QCD based on a canonical approach. A previous study has shown that such simulations are feasible, at least on sm…

Finite density simulations using a determinant estimator
Andrei Alexandru, Anyi Li, Keh-Fei Liu
Previous investigations have shown that the canonical approach to simulating QCD at finite density is promising. The algorithm we used in our earlier work employs an exact calculat…
