Description:
Author(s): Z. C. Wei, Congjun Wu, Yi Li, Shiwei Zhang, and T. Xiang The sign problem is a major obstacle in quantum Monte Carlo simulations for many-body fermion systems. We examine this problem with a new perspective based on the Majorana reflection positivity and Majorana Kramers positivity. Two sufficient conditions are proven for the absence of the fermion sign … [Phys. Rev. Lett. 116, 250601] Published Thu Jun 23, 2016
