论文摘要
在带有量子旋转的常规准中一维抗铁磁铁中，磁激发在不同的能量状态下由少量或纺纱子携带：它们不独立共存，也不能相互作用。在这封信中，通过结合非弹性中子散射，量子蒙特卡洛模拟和随机相位近似计算，我们报告了发现并讨论镁和蜘蛛共存的物理，以及它们在botallackite-cu2（OH）3br中的相互作用。这是一个独特的量子抗铁磁铁，由交替的铁磁和反铁磁自旋1/2链和链间链耦合链组成。我们的研究提出了一种新的范式，其中一个人可以研究两种不同类型的磁准粒子，镁和纺纱片之间的相互作用。
In conventional quasi-one-dimensional antiferromagnets with quantum spins, magnetic excitations are carried by either magnons or spinons in different energy regimes: they do not coexist independently, nor could they interact with each other. In this Letter, by combining inelastic neutron scattering, quantum Monte Carlo simulations and Random Phase Approximation calculations, we report the discovery and discuss the physics of the coexistence of magnons and spinons and their interactions in Botallackite-Cu2(OH)3Br. This is a unique quantum antiferromagnet consisting of alternating ferromagnetic and antiferromagnetic Spin-1/2 chains with weak inter-chain couplings. Our study presents a new paradigm where one can study the interaction between two different types of magnetic quasiparticles, magnons and spinons.
