论文摘要
量子自旋系统表现出巨大的集体激发范围,但是它们的自旋波,张开的三倍,分数旋子或其他模式通常被认为是相互排斥的。在这里,我们通过中子光谱法展示了同时出现的Magnons,Triplons和Spinon的Secuo $ _3 $。我们证明,这是由两个耦合子系统组成的结构的结果,并确定了最小磁模型的所有相互作用。我们的结果质疑可以打开多激发旋转系统的领域,并定量地限制了此类材料中一个成员的完整理论描述。
Quantum spin systems exhibit an enormous range of collective excitations, but their spin waves, gapped triplons, fractional spinons, or yet other modes are generally held to be mutually exclusive. Here we show by neutron spectroscopy on SeCuO$_3$ that magnons, triplons, and spinons are present simultaneously. We demonstrate that this is a consequence of a structure consisting of two coupled subsystems and identify all the interactions of a minimal magnetic model. Our results serve qualitatively to open the field of multi-excitation spin systems and quantitatively to constrain the complete theoretical description of one member of this class of materials.
