论文摘要
在良好的控制系统中，已经实现了1D相对论量子力学的量子模拟，但是旋转动力学和对外部磁场的响应之类的属性仅在较高维度中出现，但仍未探索。在这里，我们模拟了2D Weyl粒子的动力学。我们显示了磁场中游离粒子和离散的Landau级别的线性分散关系，并明确测量可以验证抗颗粒的螺旋性和特性的空间和自旋动力学。我们的工作扩展了离子陷阱量子模拟器在粒子物理学中的应用，并具有额外的空间和自旋程度。
Quantum simulation of 1D relativistic quantum mechanics has been achieved in well-controlled systems like trapped ions, but properties like spin dynamics and response to external magnetic fields that appear only in higher dimensions remain unexplored. Here we simulate the dynamics of a 2D Weyl particle. We show the linear dispersion relation of the free particle and the discrete Landau levels in a magnetic field, and we explicitly measure the spatial and spin dynamics from which the conservation of helicity and properties of antiparticles can be verified. Our work extends the application of an ion trap quantum simulator in particle physics with the additional spatial and spin degrees of freedom.
