Description
We study scalar QCD at nonzero density in the strong coupling limit.
It has a sign problem which looks structurally similar to the one in QCD.
After introducing dual variables by integrating out the SU(3) gauge links
we find that we need at least 3 flavors for a nontrivial dependence on the
chemical potential.
In this dual representation there is no sign problem remaining.
The dual variables are partially constrained,
thus we use a hybrid approach for the updates:
For unconstrained variables we use local updates,
while for constrained variables we use updates based on the worm algorithm.
