Normalizing Flows and the Real-Time Sign Problem

Understand

Normalizing flows have recently been applied to the problem of accelerating Markov chains in lattice field theory.

• We propose a generalization of normalizing flows that allows them to applied to theories with a sign problem.
• These complex normalizing flows are closely related to contour deformations (i.e.
• the generalized Lefschetz thimble method), which been applied to sign problems in the past.
