A sign-blocking method for mitigating the fermion sign problem
Yunuo Xiong, Hongwei Xiong
The fermion sign problem remains the primary obstacle in simulating the thermodynamic properties of various fermionic systems. In this work, we present a sign-blocking method to mi…

Simulation of strongly quantum-degenerate uniform electron gas using the pseudo-fermion method
Yunuo Xiong, Tommaso Morresi, Hongwei Xiong
For strongly quantum-degenerate systems at finite temperatures, the fermion sign problem remains the major obstacle to first-principles simulations. In this work, we apply the rece…
