Algorithm for Computing Excited States in Quantum Theory

X. Q. Luo, H. Jirari, H. Kroger, K. Moriarty

摘要:

蒙特卡罗技术已广泛应用于统计物理学以及量子理论中的拉格朗日公式。然而,在常规方法中,计算激发态是极其困难的。在这里,我们提出了一种不同的算法:蒙特卡罗哈密顿方法,旨在克服传统方法的困难。作为一个新的例子,应用克莱因-戈登场论示出。

英文摘要:

Monte Carlo techniques have been widely employed in statistical physics as well as in quantum theory in the Lagrangian formulation. However, in the conventional approach, it is extremely difficult to compute the excited states. Here we present a different algorithm: the Monte Carlo Hamiltonian method, designed to overcome the difficulties of the conventional approach. As a new example, application to the Klein-Gordon field theory is shown.
