Spin-energy Entanglement of a Neutron in MIEZE mode

We propose to demonstrate the entanglement of the spin and energy subsystems of individual neutrons with the Larmor instrument in MIEZE mode. Such neutrons could be direct probe of entanglement, which may prove to be a valuable tool in studying exotic materials. The use of MIEZE mode expands the variety of possible samples and allows the study of regimes where the neutron up and down spin states are either separated by more than the coherence length or largely overlapping.

我们提出利用MIEZE模式下的拉莫尔仪器，展示单个中子自旋与能量子系统之间的纠缠现象。这类中子可作为纠缠的直接探针，有望成为研究奇异材料的宝贵工具。MIEZE模式的应用拓展了可用样品的范围，并允许研究两种情形：中子上下自旋态的分离距离大于相干长度，或二者高度重叠。
