Alessandro Sfondrini, Javier Cerrillo, Norbert Schuch, J. Ignacio Cirac

摘要:

模拟受抑量子磁体是计算物理中最具挑战性的任务之一。我们应用弦键态,一个最近引入的模拟器,它结合了张量网络和基于Monte Carlo的方法,在二维和三维的挫折量子系统的模拟。我们比较我们的结果与现有的结果为无阻和二维系统与开放的边界条件,并证明该方法同样适用于模拟的挫折系统在二维和三维的周期性边界。

英文摘要:

Simulating frustrated quantum magnets is among the most challenging tasks in computational physics. We apply String-Bond States, a recently introduced ansatz which combines Tensor Networks with Monte Carlo based methods, to the simulation of frustrated quantum systems in both two and three dimensions. We compare our results with existing results for unfrustrated and two-dimensional systems with open boundary conditions, and demonstrate that the method applies equally well to the simulation of frustrated systems with periodic boundaries in both two and three dimensions.
