O(2N)Gross-Neveu模型的蠕虫算法

Worm algorithm for the O(2N) Gross-Neveu model

Vidushi Maillart, Urs Wenger

摘要:

本文研究了在费米子圈形式下具有Wilson费米子的格点O(2N)Gross-Neveu模型。采用蠕虫算法的开放费米子弦,我们模拟波动的拓扑边界条件,并用它们来调整系统的临界点。我们展示了如何蠕虫算法可以扩展到样本关联函数的束缚态,涉及任意数量的马约拉纳费米子和目前的第一个结果。

英文摘要:

We study the lattice O(2N) Gross-Neveu model with Wilson fermions in the fermion loop formulation. Employing a worm algorithm for an open fermionic string, we simulate fluctuating topological boundary conditions and use them to tune the system to the critical point. We show how the worm algorithm can be extended to sample correlation functions of bound states involving an arbitrary number of Majorana fermions and present first results.
