Dynamical Probes for Spin Liquids (E07*)

我们将研究量子自旋液体（QSL）的动力学特性，并模拟可以直接与实验相比较的微观模型系统。第一个课题是利用动态密度矩阵重整化群（DMRG）方法获得聚合自旋液体模型系统的动态结构因子。我们将考虑二维自旋-液体哈密顿量，包括摄动Kitaev-Heisenberg模型、自旋-1/2 kagome Heisenberg模型和三角形晶格模型。第二个主题将是理论预测量子自旋冰的动力学性质，我们将研究三维量子自旋冰的动力学结构因子。

We will investigate dynamical properties of quantum-spin liquids (QSL's) and simulate microscopic model systems that can be directly compared to experiments. The first topic is to use dynamical density matrix renormalization group (DMRG) methods to obtain dynamical structure factors of paradigmatic spin liquid model systems. We will consider 2D spin-liquid Hamiltonians including perturbed Kitaev-Heisenberg models, spin-1/2 kagome Heisenberg models, and triangular lattice models. The second topic will be to theoretically predict dynamical properties of QSL's, where we will study the dynamical structure factor of 3D quantum spin ice.
