我们提出一种算法,通过将并行回火与基于集体变量的增强采样方法相结合来解决晶格量子色动力学模拟中的拓扑冻结问题,并将其应用于具有\(N_f = 2\)交错费米子的特别具有挑战性的系统。我们发现该算法使系统解冻,否则使用有理混合蒙特卡罗算法在大约40000个分子动力学单位内系统会完全冻结。
英文摘要
We present an algorithm that addresses topological freezing in lattice QCD simulations by combining parallel tempering with collective-variable-based enhanced sampling methods, and apply it to a particularly challenging system with $N_f = 2$ staggered fermions. We find that the algorithm unfreezes the system, which is otherwise completely frozen for approximately 40000 Molecular Dynamics Units with the Rational Hybrid Monte Carlo algorithm.
