Path Integral Monte Carlo for Fictitious Identical Particles with ξ-Ensemble
Yunuo Xiong
In this work, a path integral Monte Carlo (PIMC) algorithm for fictitious identical particles (FIP) is proposed by introducing a -ensemble and performing PIMC simulations on the…
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…
A Pseudo-Fermion Propagator Approach to the Fermion Sign Problem
Yunuo Xiong, Hongwei Xiong
In this work, within the framework of path integral Monte Carlo, we construct a pseudo-fermion propagator by replacing the original fermionic determinant with its absolute value. T…
GPU acceleration of ab initio simulations of large-scale identical particles based on path integral molecular dynamics
Yunuo Xiong
Path integral Monte Carlo (PIMC) and path integral molecular dynamics (PIMD) provide the golden standard for the ab initio simulations of identical particles. In this work, we achi…
