AI 中文摘要
近期提出的自发退纠缠假设通过添加非线性项的修正薛定谔方程来表述，该假设的动机源于量子力学基础中的若干突出问题，包括量子测量问题。本研究针对宏观极限探究自发退纠缠，采用具有已知精确解的多体模型开展研究。对于所研究的模型，发现非局域纠缠在宏观极限下是不稳定的；另一方面，局域纠缠在宏观极限下的稳定性并未被排除。这些发现表明，自发退纠缠假设能够在微观领域的量子性与宏观领域的经典性之间搭建桥梁。
英文摘要
The recently proposed spontaneous disentanglement hypothesis is formulated using a modified Schrödinger equation having an added nonlinear term. The hypothesis is motivated by some outstanding issues in the foundations of quantum mechanics, including the problem of quantum measurement. Spontaneous disentanglement is explored in the current study for the macroscopic limit. This is done using some many--body models having known exact solutions. For the under--study models, it is found that non--local entanglement becomes unstable in the macroscopic limit. On the other hand, stability in the macroscopic limit of local entanglement is not excluded. These findings demonstrate that the spontaneous disentanglement hypothesis can bridge between the quantumness of the microscopic realm, and the classicalness of the macroscopic one.
