量子拉比模型描述了两能级量子系统与单个玻色子模之间的相互作用。我们提出了一种方法来执行量子拉比模型的量子模拟，介绍了实施的两个级别的系统提供的超冷原子在定制的光学晶格中的第一布里渊区的布洛赫带的占用。有效量子比特与在光偶极阱中实现的量子谐振子相互作用。我们现实的建议允许一个实验研究极端参数制度，这是无法实现的自然光物质相互作用的量子拉比模型。当模拟的波函数超过模拟的有效区域时，我们在周期相空间中识别出量子拉比模型的广义版本。
The quantum Rabi model describes the interaction between a two-level quantum system and a single bosonic mode. We propose a method to perform a quantum simulation of the quantum Rabi model, introducing an implementation of the two-level system provided by the occupation of Bloch bands in the first Brillouin zone by ultracold atoms in tailored optical lattices. The effective qubit interacts with a quantum harmonic oscillator implemented in an optical dipole trap. Our realistic proposal allows one to experimentally investigate the quantum Rabi model for extreme parameter regimes, which are not achievable with natural light-matter interactions. When the simulated wave function exceeds the validity region of the simulation, we identify a generalized version of the quantum Rabi model in a periodic phase space.
