Description
Lefschetz-thimble method is a recently developing tool to evaluate the path integral with the sign problem. In the case of finite-density QCD and its effective models, the fermion sign problem causes some illness even within the mean-field approximation. We showed that the sign problem appearing in the mean-field approximation can be completely solved by applying this technique. We will consider its application to the heavy-dense quark system in order to demonstrate its usefulness.
