标题： Zeeman Ladders in Frustrated XYZ Spin Chains

摘要： 我们研究了XYZ三角形自旋-1/2梯子动力响应所捕捉到的激发性质。 我们将化合物$\text{Cs}_\text{2}\text{CoBr}_\text{4}$的实验非弹性中子散射结果与基于时间依赖矩阵乘积态方法的数值精确模拟相结合。 我们的结果表明，在XYZ体系中，自旋子激发的束缚态可以在不需要强伊辛各向异性的条件下出现。 我们分析了受挫三角耦合在激发中的作用，这些激发导致了自旋动力学结构因子，并展示了束缚态的特征如何在不同的极化通道中表现出来。 显示英文摘要

摘要： We investigate the nature of the excitations captured by the dynamical response of XYZ triangular spin-1/2 ladders. We complement experimental inelastic neutron scattering results on the compound $\text{Cs}_\text{2}\text{CoBr}_\text{4}$ with numerically exact simulations based on time-dependent matrix product state methods. Our results show that bound states of spinon excitations can arise in XYZ beyond the requirement of strong Ising anisotropies. We analyze the role of the frustrated triangular couplings on the excitations giving rise to the spin dynamical structure factor and show how the features of the bound states manifest themselves in the different polarization channels.
