论文摘要
我们认为自旋链星系具有N-Wise多体相互作用的特征，每个链中的旋转之间的多体相互作用。我们表明，可以通过单一转换将此类系统精确地映射到标准的自旋系统中。这种方法可以基于链之间的纠缠概念来解决XX自旋星模型的动态问题，并透明地显示系统中量子相关性的出现。
We consider spin-chain-star systems characterized by N-wise many-body interactions between the spins in each chain and the central one. We show that such systems can be exactly mapped into standard spin-star systems through unitary transformations. Such an approach allows the solution of the dynamic problem of an XX spin-chain-star model and transparently shows the emergence of quantum correlations in the system, based on the idea of entanglement between chains.
