论文摘要
我们研究了最近提出的具有附加非线性项的修改后的Schrödinger方程。对于将随机项添加到哈密顿量的情况下,发现波动的响应类似于热化过程。对于由两个耦合旋转制成的系统,探索了由添加的非线性术语引起的分离。在自旋旋转系统的完全纠缠状态附近发现了类似蝴蝶的效果。当一个旋转是外部驱动时,发现了一个极限循环解决方案。
We study a recently proposed modified Schrödinger equation having an added nonlinear term. For the case where a stochastic term is added to the Hamiltonian, the fluctuating response is found to resemble the process of thermalization. Disentanglement induced by the added nonlinear term is explored for a system made of two coupled spins. A butterfly-like effect is found near fully entangled states of the spin-spin system. A limit cycle solution is found when one of the spins is externally driven.
