概要

We develop a way of improving complex Langevin dynamics motivated by the Lefschetz-thimble decomposition of integrals. In this talk, we consider the cosine model which has a global sign problem due to its multi-thimble structure. We show that the toy model can be modified so that the new model consists of a single Lefschetz thimble and the configurations sampled by the improved complex Langevin process are distributed around on the thimble.
