散射过程中纠缠熵的变化

Variation of Entanglement Entropy in Scattering Process

I. Y. Park, Shigenori Seki, Sang-Jin Sin

摘要:

在散射过程中,最终状态由初始状态和S-矩阵确定。我们专注于两个粒子的散射过程,并考虑这些粒子之间的纠缠。对于两种类型的初始状态,即,一个非纠缠态和一个纠缠态,微扰计算了从初始态到最终态的纠缠熵的变化。然后,我们给出场论和量子力学中的几个例子。

英文摘要:

In a scattering process, the final state is determined by an initial state and an S-matrix. We focus on two-particle scattering processes and consider the entanglement between these particles. For two types initial states; i.e., an unentangled state and an entangled one, we calculate perturbatively the change of entanglement entropy from the initial state to the final one. Then we show a few examples in a field theory and in quantum mechanics.
