量子嵌合态

Quantum chimera states

David Viennot, Lucile Aubourg

摘要:

我们研究了一个封闭的准厄米自旋链的理论模型,该模型表现出嵌合态的量子类似物,即长寿命的经典态,其中一部分振子链呈现有序动力学,而另一部分呈现无序混沌动力学。对于量子模拟,嵌合体行为处理的是链的自旋之间的纠缠。我们讨论了量子嵌合体系统的纠缠特性、量子混沌、量子无序和半经典相似性。量子嵌合体的概念是一个新的概念,它为多体系统的纠缠研究提供了新的视角。

英文摘要:

We study a theoretical model of closed quasi-hermitian chain of spins which exhibits quantum analogues of chimera states, i.e. long life classical states for which a part of an oscillator chain presents an ordered dynamics whereas another part presents a disordered chaotic dynamics. For the quantum analogue, the chimera behavior deals with the entanglement between the spins of the chain. We discuss the entanglement properties, quantum chaos, quantum disorder and semi-classical similarity of our quantum chimera system. The quantum chimera concept is novel and induces new perspectives concerning the entanglement of multipartite systems.
