均匀分布费米系统的组态路径积分蒙特卡罗模拟
Configuration path integral Monte Carlo simulations of uniform fermion systems
摘要
Abstract
The sampling process of Configuration Path Integral Monte Carlo was simplified.Non－interacting os-cillator and uniform electron gas were simulated by the corresponding code.Energy distributions of both Fermi systems match well with Fermi－Dirac distribution.Momentum distributions of uniform electron gas under differ-ent temperatures and densities also match well with Fermi－Dirac distribution.The research on the two Fermi systems indicates that Configuration Path Integral Monte Carlo shows great potential for solving Fermi sign prob-lem.We present an alternative for Fermi sign problem.And did some remarkable work on uniform electron gas,which lays a foundation for further study for warm－dense matter.关键词
