Description
We discuss two methods for simulating systems with a
"theta-like" term in the action, and that therefore suffer from a
severe sign problem. Both methods are based on simulations at
imaginary values of the "theta-like" parameter, where the sign problem
is absent. We show the results of implementing the methods in a
variety of physical systems, and we analyze their applicability and
shortcomings. We also present preliminary results on the Schwinger
model with a theta term, and we discuss the prospects for simulating
QCD with a non-zero theta angle.
