Description
Lattice simulations of non-zero density QCD introduce the so-called sign problem (complex or negative probabilities), which invalidates importance sampling methods. We use the Complex Langevin equation (CLE) to circumvent the sign problem, measure boundary terms and use reweighting to test the reliability of the boundary term observable, confirming expectations from previous studies.
We also investigate boundary terms in simulations using CLE with dynamic stabilization and compare this, to results calculated with reweighting.
