论文摘要
在粒子物理学中开发的超对称性的概念已应用于现代物理的各个领域。在量子力学中,超对称系统是指涉及两个超对称伴侣汉密尔顿人的系统,其能量水平是堕落的,除了一个系统可能具有额外的基态,并且可以将伴侣系统的本征状态映射到对方。最近,已经提出了一种干涉方案来显示超低原子中的这种关系[物理学。 Rev.A 96,043624(2017)]。在这里,这种方法推广到线性光学器件,用于观察具有光子的超对称动力学。通过Suzuki-Trotter的扩展大致模拟了时间演化运算符,并分别考虑了动力学和潜在项的实现。前者是通过光的衍射性实现的,然后使用相板实现了后者。此外,我们提出了一种干涉方法,可以使用振幅交流发电机完美地实现,以实现非自动运算符。数值结果表明我们的方案是通用的,可以通过当前技术实现。
The concept of supersymmetry developed in particle physics has been applied to various fields of modern physics. In quantum mechanics, the supersymmetric systems refer to the systems involving two supersymmetric partner Hamiltonians, whose energy levels are degeneracy except one of the systems has an extra ground state possibly, and the eigenstates of the partner systems can be mapped onto each other. Recently, an interferometric scheme has been proposed to show this relationship in ultracold atoms [Phys. Rev.A 96, 043624 (2017)]. Here this approach is generalized to linear optics for observing the supersymmetric dynamics with photons. The time evolution operator is simulated approximately via Suzuki-Trotter expansion with considering the realization of the kinetic and potential terms separately. The former is realized through the diffraction nature of light and the later is implemented using phase plate. Additionally, we propose an interferometric approach which can be implemented perfectly using amplitude alternator to realize the non-unitary operator. The numerical results show that our scheme is universal and can be realized with current technologies.
